Crochet Cardigan & Shorts Set Pattern 🌿 Colorful Granny Stripe Summer Outfit
There is something so satisfying about finishing a crochet project that you can actually wear, and a matching set takes that feeling to a whole new level. This colorful granny stripe cardigan and shorts set is one of those projects that turns heads at the farmers market, earns compliments at the beach, and makes you feel like you designed it yourself — because you did. Whether you are brand new to garment crochet or you have been making wearables for years, this pattern is written to guide you through every step with clear instructions, helpful tips, and plenty of room to make it your own.
The granny stripe stitch is one of the most beloved techniques in the crochet world for good reason. It is beginner-friendly, works up quickly, and creates that beautiful textured stripe effect that looks far more complex than it actually is. When you pair it with a breezy linen-blend yarn and a palette of summer colors, the result is a set that feels both boho and modern, casual and intentional.
Let us dive in.
Why You Will Love This Pattern
Before we get into the materials and instructions, let us talk about what makes this particular set so special and why so many crocheters keep coming back to granny stripe designs season after season.
First, the versatility is unmatched. The cardigan in this set works as a layering piece over a swimsuit, a breezy cover-up at an outdoor concert, or a lightweight layer on cool summer evenings. The matching shorts can be worn over a swimsuit at the pool, paired with a tank top for a casual brunch look, or styled with sandals for a full-on handmade fashion moment.
Second, the color opportunities are genuinely endless. The granny stripe technique is designed to be worked in stripes, which means every row can be a different color or you can repeat a sequence for a more rhythmic look. This pattern uses a six-color palette inspired by wildflower meadows — sage green, dusty rose, warm cream, terracotta, sky blue, and golden yellow — but you are absolutely free to swap those out for whatever makes your heart sing.
Third, this is a stash-busting project. If you have been collecting partial skeins of cotton or linen-blend yarn the way many crocheters do, this set is the perfect opportunity to put them all to use. You do not need enormous amounts of any single color, which means you can dig into those leftover skeins and come out with something cohesive and beautiful.
Materials You Will Need
To make this cardigan and shorts set, gather the following before you begin. Having everything prepared ahead of time makes the process much more enjoyable.
Yarn: Approximately 800 to 1,000 yards total of a DK or light worsted weight cotton or linen-blend yarn, divided among your chosen colors. For a six-color palette, aim for about 150 to 170 yards per color. Brands that work beautifully for this pattern include Lion Brand 24/7 Cotton, Paintbox Yarns Simply DK, and Drops Safran. If you want a softer drape, look for a cotton-linen or cotton-bamboo blend.
Hook: A US size G/4.0mm crochet hook or H/5.0mm depending on your personal tension. The key is to match your gauge, not the hook size written on the label.
Notions: A yarn needle for weaving in ends, scissors, stitch markers, a measuring tape, and approximately one yard of elastic (3/4 inch wide) for the shorts waistband.
Gauge: For this pattern, your gauge should be approximately 16 stitches and 8 rows per 4 inches in the granny stripe stitch pattern. Take the time to swatch before beginning. Garment fit depends on accurate gauge, and five minutes of swatching can save hours of frustration later.
Sizing: This pattern is written for sizes XS through 3XL. The cardigan is designed with a relaxed, open-front silhouette that is forgiving on fit. The shorts are worked with an elastic waistband, which also allows for some flexibility.
Understanding the Granny Stripe Stitch
If you have crocheted a granny square before, the granny stripe stitch will feel immediately familiar. Instead of working in the round, you work back and forth in rows, creating clusters of double crochet stitches separated by chain spaces. The result is a textured, airy fabric with those iconic little peaks and valleys that define the granny aesthetic.
Here is how to work the granny stripe stitch row by row.
Foundation: Chain a multiple of four plus three. For example, for the cardigan back panel, you will chain 75 for a size medium.
Row 1 (right side): In the 4th chain from the hook, work 2 double crochets. Skip 2 chains. In the next chain, work (3 double crochets, chain 2, 3 double crochets). This creates your first granny cluster with a corner space. Continue across by skipping 2 chains and working 3 double crochets in the next chain. At the end of the row, skip 2 chains and work 3 double crochets in the last chain. Turn.
Row 2: Chain 3 (counts as first double crochet). Work 2 double crochets in the same stitch. Skip to the next chain-2 space and work (3 double crochets, chain 2, 3 double crochets). Continue across. End with 3 double crochets in the turning chain space. Turn.
Row 3 and beyond: Repeat Row 2, changing colors as desired at the end of each row by pulling the new color through the last two loops of the final stitch in the row.
The beauty of this stitch is that once you have completed your first few rows, your hands will find the rhythm and you will be able to work almost without thinking, which makes it a perfect project to bring to social gatherings or work on while watching your favorite show.
The Cardigan Pattern
Sizing and Measurements
Before beginning, determine your size based on your finished bust measurement. The cardigan is an open-front style with no closures, designed to be worn with approximately 4 to 6 inches of positive ease for a relaxed, flowy fit.
XS: 30–32″ bust (finished width 36″)
S: 33–35″ bust (finished width 40″)
M: 36–38″ bust (finished width 44″)
L: 39–41″ bust (finished width 48″)
XL: 42–44″ bust (finished width 52″)
2XL: 45–47″ bust (finished width 56″)
3XL: 48–50″ bust (finished width 60″)
Back Panel
Chain the appropriate number for your size: XS chain 51, S chain 63, M chain 75, L chain 87, XL chain 99, 2XL chain 111, 3XL chain 123.
Work in the granny stripe stitch pattern, changing colors every one to two rows, until the back panel measures 14 inches from the foundation chain. This is your back body length. Set aside and weave in all ends except the working end.
Front Panels (Make Two, Mirror Images)
Each front panel is worked to approximately half the width of the back panel. Chain 27 (XS), 33 (S), 39 (M), 45 (L), 51 (XL), 57 (2XL), or 63 (3XL).
Work in the granny stripe stitch using the same color sequence as the back panel until each front panel measures 14 inches, matching the back exactly. Set aside.
Sleeves (Make Two)
The sleeves on this cardigan are three-quarter length, which is the perfect balance of coverage and breathability for summer. They are worked in the round after the body is seamed together, which gives them a clean, professional finish.
First, seam the back panel to the two front panels at the shoulder seams. Leave the sides open at this stage. With right sides facing, place the back panel and one front panel together and slip stitch through both layers along the top 4 to 5 inches of each side. Repeat for the second front panel on the other shoulder.
To begin a sleeve, join your yarn at the armhole edge and work in the round in the granny stripe stitch, joining each round with a slip stitch and chaining 3 to begin the next. Work until the sleeve measures 12 to 14 inches from the armhole. Fasten off and weave in ends.
Side Seams and Finishing
Seam the sides of the cardigan from the hem up to where the sleeves begin, leaving a few inches open at the top for your armhole. The exact opening length will depend on your size — generally 6 to 8 inches for most sizes.
For the edging, join your yarn at the bottom center back and work a single round of single crochet all the way around the hem of the cardigan, up along one front edge, around the neckline, and down the other front edge. This gives the cardigan a clean, finished look without adding bulk. You can also add a row of reverse single crochet (also called the crab stitch) for a more polished edging.
Block your finished cardigan by soaking it in cool water, gently squeezing out excess moisture, and laying it flat to dry. Blocking is especially important for cotton and linen blends because it opens up the stitches and gives the fabric a beautiful, even drape.
The Shorts Pattern
The matching shorts are worked in rows to create two panels (front and back), which are then seamed together and finished with an elastic waistband. They are a simple, flattering shape that suits a wide range of body types.
Sizing for the Shorts
XS: 24–26″ hip (finished hip 30″)
S: 27–29″ hip (finished hip 34″)
M: 30–32″ hip (finished hip 38″)
L: 33–35″ hip (finished hip 42″)
XL: 36–38″ hip (finished hip 46″)
2XL: 39–41″ hip (finished hip 50″)
3XL: 42–44″ hip (finished hip 54″)
Front and Back Panels (Make Two)
For the shorts, each panel is worked as a rectangle to the hip measurement divided by two, plus ease. Chain 39 (XS), 51 (S), 63 (M), 75 (L), 87 (XL), 99 (2XL), or 111 (3XL).
Work in the granny stripe stitch using your chosen color sequence until the panel measures 10 to 12 inches from the foundation chain, depending on your preferred inseam length. A 10-inch panel gives you a shorter, more fitted short, while 12 inches gives you a bit more coverage and a Bermuda-style silhouette.
Shaping the Legs
To create the curved leg opening that gives the shorts their shape, you will work a simple decrease at the lower edges of each panel. At the beginning and end of the last 4 rows, decrease by skipping the first cluster and ending one cluster before the final stitch. This gently curves the lower edge to create the leg opening shape. You can also leave the panels as rectangles if you prefer a boxier, more relaxed silhouette.
Assembly
Place the two panels together with right sides facing and seam along both side edges using a slip stitch or whip stitch. Then, to create the crotch seam, fold the shorts so that the side seams meet in the center. Seam along the lower curved edge of each leg, working from the center front to the center back on each side. Turn right side out and try on to check the fit before completing the waistband.
Waistband
Fold the top edge of the shorts down approximately 1.5 inches toward the inside to create a waistband channel. Using your yarn needle and a length of yarn, whip stitch the folded edge down, leaving a 1-inch opening at the back seam. Thread your elastic through the channel using a safety pin, overlap the ends by about half an inch, and stitch the ends together securely. Close the opening with a few whip stitches.
As an alternative, you can work a crocheted waistband by picking up stitches along the top edge and working several rows of ribbing-style single crochet through the back loop only. This creates a stretchy, comfortable waistband that does not require elastic and adds to the handmade feel of the garment.
Color Palette Ideas
One of the most enjoyable parts of planning a granny stripe project is choosing your color palette. Here are a few combination ideas to get your creativity flowing.
A desert sunset palette might include burnt orange, deep rust, warm peach, dusty mauve, and cream. This combination feels earthy and warm and pairs beautifully with natural-toned sandals and linen accessories.
A tropical palette might feature bright coral, turquoise, lime green, sunshine yellow, and white. This high-contrast combination is bold and playful, perfect for a beach vacation or a summer festival.
A muted, sophisticated palette might use sage green, dusty lavender, pale blush, warm stone, and soft white. This combination feels grown-up and versatile, working just as well at a farmers market as it does at a rooftop dinner.
A monochromatic palette working through several shades of a single color — for example, five or six shades of blue from palest sky to deep navy — creates a subtle, wave-like effect that is quietly stunning and unexpectedly elegant.
Tips for Success
A few things will make your experience with this pattern smoother and more enjoyable from start to finish.
Weave in your ends as you go rather than saving them all for the end. With a multicolor stripe project, ends accumulate quickly, and dealing with a dozen or more at the finish line can feel overwhelming. Taking a moment every few color changes to weave in the previous ends keeps everything manageable.
Use stitch markers generously. Even experienced crocheters can lose track of their stitch count when working on a longer row. Place a marker every twenty stitches and check in periodically to make sure your count is on track.
Take photographs of your swatch next to a ruler before you begin. If you ever need to adjust your hook size or revisit your gauge calculations, having a reference photo is incredibly helpful.
Do not skip blocking. This is the single most transformative step in garment finishing, and it costs almost nothing. Cotton and linen yarns in particular open up beautifully when blocked, and the finished fabric will look as if it came from a boutique rather than your own hands.
Styling Your Finished Set
Once your cardigan and shorts set is complete, the fun of styling it begins. For a beachy look, layer the cardigan open over a simple white swimsuit or ribbed bikini. Add a wide-brim hat, wooden bangles, and woven sandals to complete the outfit.
For a more dressed-up summer look, pair the shorts with a tucked-in fitted camisole in a neutral color, then layer the cardigan over it. Block-heeled sandals or espadrilles elevate the whole ensemble in a way that feels effortless.
For a casual, everyday look, wear the full set together with flat sandals and a canvas tote. The matching granny stripe pieces read as a coordinated outfit without looking overly matchy, because the multicolor stripe design contains enough variation to keep everything visually interesting.
Final Thoughts
A handmade wardrobe piece is always more than just something to wear. It is a record of time spent, a demonstration of skill, and a creative expression that no fast-fashion purchase can replicate. This colorful granny stripe cardigan and shorts set is the kind of project you will want to make in multiple colorways, the kind that gets photographed and shared and asked about, and the kind that reminds you — every time you put it on — why you fell in love with crochet in the first place.
Take your time with it. Enjoy the rhythm of the stitch and the joy of watching your color palette come together row by row. And when you are finished, wear it with the particular pride that only a maker understands.
Happy crocheting! 🌿
