Crochet Co-Ord Set Pattern: Blue Crochet Top & Wide Leg Pants PDF Pattern

There is something undeniably satisfying about creating a complete outfit from scratch — two pieces that belong together, that were made with the same yarn, the same intention, and the same hands. A crochet co-ord set brings that satisfaction to a whole new level. When you slip on a matching top and wide leg pants you made yourself, the feeling is incomparable. This pattern guide walks you through everything you need to know to create a stunning blue crochet co-ord set: a breezy, textured top paired with flowing wide leg pants. Whether you are an intermediate crocheter looking for a rewarding project or someone who wants to expand their wardrobe with handmade pieces, this is the project for you.

Why Crochet Co-Ord Sets Are Having a Moment

Matching sets have taken over fashion in a big way, and the handmade crochet version is at the heart of that trend. What makes crochet co-ords so special compared to their store-bought counterparts is the ability to customize absolutely everything — the fit, the color, the stitch texture, and the length. You are not buying off a rack. You are building something tailored to your body and your taste.

The blue crochet co-ord set in particular has become one of the most searched and beloved colorways in the crochet fashion community. Blue works across all skin tones, it photographs beautifully in natural light, and it carries that effortless coastal, resort-inspired energy that feels relevant season after season. From soft baby blue to rich cobalt to deep navy, this color family gives you room to make the set your own while keeping the overall aesthetic cohesive and striking.

Wide leg pants paired with a cropped or fitted top are also one of the most flattering silhouettes in contemporary fashion. The wide leg creates a long, elegant line, balances the proportions of the body, and moves beautifully when walking. When crocheted in a lightweight yarn, these pants drape with a relaxed, luxurious quality that no pair of store-bought pants can quite replicate.

Materials You Will Need

Before you pick up your hook, gathering the right materials will set you up for success. Here is a complete list of what this pattern requires.

Yarn: The ideal yarn for this project is a lightweight cotton or cotton-blend yarn in a medium blue shade of your choice. Cotton works best for garments because it has minimal stretch, drapes well, holds stitch definition, and breathes in warmer weather — which is exactly what you want for a co-ord set that you will likely wear in spring and summer. You will need approximately 800 to 1,000 yards of yarn for the top and 1,500 to 2,000 yards for the wide leg pants, depending on your size. A size 10 crochet thread or DK weight cotton yarn gives a beautiful, slightly open fabric that still maintains structure.

Hook: A 4.0mm or 4.5mm crochet hook works best with most DK weight cotton yarns. Always crochet a gauge swatch before starting the garment pieces so you can adjust your hook size if needed. Gauge is non-negotiable for garment projects — even a small difference per stitch adds up significantly across the width of a full garment.

Notions: You will need a yarn needle for weaving in ends, scissors, stitch markers, a measuring tape, and an elastic waistband or drawstring cord for the pants. If you want the top to have a more structured look, you can also add a thin piece of ribbon or elastic to the hem or neckline.

Gauge: For this pattern, the target gauge is approximately 18 stitches and 20 rows per 4 inches in the main stitch pattern using a 4.0mm hook. Crochet a 6-inch swatch, wash and block it, then measure. This step is worth every minute it takes.

Understanding the Stitch Pattern

This co-ord set uses a combination of two main stitch patterns that create visual interest while keeping the fabric light and airy.

For the top: The main body uses a simple mesh stitch — a combination of chain spaces and single or double crochets that creates an open, lattice-like fabric. This adds a beautiful texture and allows the top to breathe. The hem and neckline edges are finished with a row of crab stitch (also called reverse single crochet), which gives a clean, professional finish without adding bulk.

For the pants: The wide leg pants use a combination of half double crochet and shell stitches. The waistband is worked in ribbed single crochet (working into the back loop only) to create stretch and recovery, which keeps the waistband comfortable and secure. The legs transition into a relaxed shell pattern that fans out as you work down, creating that characteristic wide leg silhouette.

If you are unfamiliar with any of these stitches, here is a quick reference:

Mesh stitch: Chain 3, skip 2 stitches, single crochet into the next stitch, repeat across. On return rows, work chain 3 and single crochet into each chain space. This creates a diamond grid.

Shell stitch: Work 5 double crochets into a single stitch or chain space. Skip 2 stitches on either side. This creates a fan shape that naturally expands the fabric width.

Back loop only (BLO) ribbing: Work single crochets into the back loop only of each stitch. This creates a horizontal rib texture with natural stretch.

Crab stitch: Work single crochet from left to right instead of the usual right to left direction. This creates a twisted, rope-like edging.

The Crochet Top Pattern

Sizing

This pattern is written for sizes XS through XL, with adjustments explained for each section. The finished bust measurement for each size is approximately:

XS: 32 inches, S: 34 inches, M: 36 inches, L: 40 inches, XL: 44 inches.

The top is designed to have a relaxed fit with approximately 2 to 4 inches of positive ease. If you prefer a more fitted look, size down. If you prefer an oversized style, size up.

Instructions

Foundation: Chain a multiple of 3 plus 2. For a size medium, chain 98.

Row 1: Single crochet in the 2nd chain from hook and in each chain across. Turn. (97 stitches)

Row 2: Chain 3, skip the first 2 stitches, single crochet in the next stitch. Chain 2, skip 2, single crochet in the next stitch. Repeat from to across. Turn.

Row 3: Chain 3, single crochet in the first chain-2 space. Chain 2, single crochet in the next chain-2 space. Repeat across, ending with single crochet into the turning chain space. Turn.

Repeat Row 3 until the piece measures approximately 14 inches from the foundation chain for a cropped length, or 16 inches for a standard length.

Armhole shaping: Slip stitch across the first 4 spaces, then work in pattern across until 4 spaces remain. Turn and continue in pattern across the center section. Work 6 to 8 rows straight for the armhole depth, then begin joining the shoulder sections.

Shoulders and neckline: Work each shoulder separately for approximately 4 rows, then fasten off. Join a new strand of yarn for the second shoulder and work to match.

Assembly: With right sides facing, join the shoulder seams and side seams using a whipstitch or slip stitch seam through both loops. A whipstitch gives a flat seam that is barely visible on the inside.

Finishing: Work one row of single crochet evenly around the neckline and armholes to stabilize the edges, then finish with a row of crab stitch for the decorative rolled edging. Do the same around the bottom hem of the top.

The Wide Leg Pants Pattern

The pants are worked from the waistband down, which allows you to try them on as you go and adjust the length easily.

Sizing

The finished waist measurement (unstretched) for each size is approximately:

XS: 24 inches, S: 26 inches, M: 28 inches, L: 32 inches, XL: 36 inches.

The pants are designed to be worn with a drawstring or elastic at the waist, which means they can accommodate a range of waist sizes. Measure your natural waist or hip (whichever you prefer to sit the waistband at) and choose your size accordingly.

Waistband

Foundation: Chain 20.

Row 1: Single crochet in the 2nd chain from hook and each chain across. (19 stitches)

Row 2: Chain 1, single crochet in the back loop only of each stitch across. Turn.

Repeat Row 2 until the waistband measures the full circumference of your waist or hip (unstretched), minus about 2 inches to account for the natural stretch of ribbing. For a size medium with a 28-inch waist, you would work the waistband until it measures approximately 26 inches long.

Fold the waistband in half lengthwise and join the short ends with a slip stitch seam to form a tube. This becomes the waistband ring.

Body of the Pants

Join yarn to the long edge of the waistband ring and work in rounds.

Round 1: Work a foundation row of half double crochets evenly around the top edge of the waistband — approximately 100 to 140 stitches depending on your size. Place a stitch marker at the center back to track your rounds.

Rounds 2 through 15: Work in half double crochet in the round, maintaining the stitch count. This creates the hip section of the pants, which should be approximately 10 to 12 inches long before the crotch split.

Creating the Crotch and Leg Sections

At the crotch, you will divide the pants into two separate legs.

Divide your total stitch count in half. For a 120-stitch round, each leg begins with 60 stitches. Join a length of yarn to the center front and crochet a chain of 8 to 10 stitches across the crotch opening, then join to the center back. This chain bridges the gap between the front and back and becomes the inner seam of the crotch.

Now work each leg separately in joined rounds.

Round 1 of leg: Beginning at the center crotch, single crochet across the chain stitches, then work half double crochet around the leg opening and join. You will now have approximately 70 to 80 stitches around each leg circumference depending on your size.

Wide Leg Shaping

This is where the dramatic wide leg silhouette is created. Over the next several inches, you will increase the stitch count to create the flare.

Increase rounds: Every 4 rounds, add a shell stitch at each side seam point to increase the width. Work a shell stitch (5 double crochets) into the stitch at each side point instead of a single half double crochet. This adds 8 stitches to the leg circumference every 4 rounds.

Continue until the leg circumference is approximately 50 to 60 inches, depending on how dramatic a wide leg you prefer. A 50-inch circumference gives a relaxed, modern wide leg. A 60-inch circumference gives a more theatrical, palazzo-style flare.

Leg length: Continue working in the shell and half double crochet pattern until the leg measures your desired inseam length. For a full-length trouser, an inseam of 28 to 30 inches is standard. For a wide leg crop pant, work to approximately 24 inches.

Hem: Work one round of single crochet around the bottom of each leg, then finish with one round of crab stitch. This stabilizes the hem and gives a beautiful, professional finish that mirrors the edging on the top.

Adding the Drawstring

Using a yarn needle, thread a length of twisted cord (which you can make by cutting a length of yarn, folding it in half, and twisting it tightly before allowing it to coil back on itself) through the waistband ribbing, alternating between the front and back loops to create a woven effect. Leave enough cord on each end to tie a bow at the center front. Alternatively, thread a 1-inch-wide elastic through the waistband channel for a cleaner, more tailored look.

Blocking and Finishing Your Co-Ord Set

Blocking is the step that transforms a handmade crochet piece from something that looks homemade into something that looks like it belongs in a boutique. For cotton yarn, wet blocking is the most effective method.

Fill a basin with cool water and submerge both pieces. Allow them to soak for 15 to 20 minutes until fully saturated. Gently squeeze out the water without wringing, then roll each piece in a clean towel to remove excess moisture. Lay them flat on a blocking mat or clean surface, pinning or shaping them to the correct measurements. Allow to dry completely before wearing.

After blocking, weave in all remaining yarn ends with your needle, taking care to secure them by weaving back and forth in different directions through the stitches. This prevents ends from coming loose with wear and washing.

Tips for Customizing This Pattern

One of the greatest joys of making your own clothes is the ability to make them completely yours. Here are a few ways to customize this co-ord set.

You can work the top in a longer length for a more modest, flowy look, or add a front slit at the hem for a fashion-forward touch. Adjusting the neckline from a simple round neck to a V-neck is as simple as working a decrease at the center front as you build the body rows.

For the pants, you can add a contrast-color waistband in a complementary shade — white or cream against a deep blue looks stunning — or crochet the hem in a contrasting shade to add a color-blocked element. You could also work the shell stitch sections in a different blue tone to create an ombre effect as the leg widens.

The mesh stitch on the top can be scaled up for a more open, beachy look by using larger chain spaces, or scaled down for a denser fabric that offers more coverage.

Caring for Your Crochet Co-Ord Set

Cotton yarn is generally very easy to care for. Hand wash in cool water with a gentle detergent, or machine wash on a delicate cycle in a mesh laundry bag. Lay flat to dry to maintain the shape and prevent stretching. Avoid wringing or twisting the fabric, as this can distort the stitches.

With proper care, a well-made crochet garment will last for years and only get softer and more beautiful with washing.

Final Thoughts

Creating a crochet co-ord set is one of those projects that feels ambitious at the start and deeply rewarding at the finish. The blue crochet top and wide leg pants pattern is designed to be worked through in stages — each piece on its own is manageable, and the moment you put them together for the first time is genuinely thrilling.

Whether you wear this set to the beach, to a summer lunch, or simply around the house on a warm afternoon, you will wear it knowing you made it. Every stitch is yours. Every choice — the shade of blue, the length of the legs, the weight of the yarn — reflects your own creativity and skill.

That is what handmade fashion is really about. Not just the finished piece, but the entire process of building something beautiful from a single strand of yarn.

Happy crocheting.
