Leona Fan Summer Vest: Free Crochet Pattern for a Breezy, Stylish Season

There is something deeply satisfying about wearing something you made with your own hands. When that something is also lightweight, beautiful, and perfect for warm weather, the satisfaction doubles. The Leona Fan Summer Vest is exactly that kind of project — a free crochet pattern that combines a classic fan stitch with a modern, wearable silhouette. Whether you are a seasoned crocheter looking for a quick summer make or an intermediate crafter ready to try a garment for the first time, this pattern has everything you need to create a piece you will reach for all season long.

In this post, we are going to walk through the full free pattern for the Leona Fan Summer Vest, including materials, sizing, stitch instructions, and construction notes. We will also talk about yarn substitutions, blocking tips, and ways to style the finished vest so you get the most out of every wear.

What Makes the Leona Fan Summer Vest Special

Fan stitches have been a staple of crochet for generations. They create an open, lacy texture that is both visually striking and incredibly practical for summer garments because the spaces in the stitch allow air to move freely against your skin. The Leona vest takes that timeless fan pattern and applies it in a way that feels fresh and current — fitted enough to be flattering, loose enough to layer over a tank top or swimsuit cover-up, and simple enough in construction that you will not need to sew a dozen seams to finish it.

The name Leona nods to the lion-like quality of the fan stitch itself, which fans outward in broad, sweeping arcs that resemble a mane. It is a bold stitch worn with ease, and that contradiction is exactly what makes this vest so appealing. It looks intricate but works up quickly. It photographs beautifully but feels effortless to wear.

Materials You Will Need

Before you cast on — or rather, chain up — gather your supplies. The Leona Fan Summer Vest is designed with warm-weather fibers in mind, so yarn choice matters a great deal here.

Yarn: You will need approximately 400–600 yards of a DK or light worsted weight yarn, depending on your size. Cotton, cotton blends, bamboo, or linen yarns are ideal because they are breathable and have a beautiful drape. Avoid anything too fuzzy or bulky, as it will fill in the fan stitch openings and lose that airy effect. Some excellent choices include Lion Brand 24/7 Cotton, We Are Knitters The Cotton, Paintbox Simply DK, or any affordable cotton DK you find at your local craft store.

Hook: A 4.5mm (US size 7) crochet hook is recommended for most yarn weights in this range. Adjust up or down as needed to match gauge.

Notions: A yarn needle for weaving in ends, scissors, stitch markers, and a measuring tape.

Optional: Buttons or a decorative clasp if you prefer a front closure, though the pattern is written as an open front vest.

Gauge and Sizing

Gauge is especially important in garment making. For this pattern, you are aiming for one fan repeat (which equals 6 stitches) spanning approximately 1.5 inches, and 8 rows measuring approximately 4 inches in height using the fan stitch pattern. Take time to make a swatch and adjust your hook size accordingly.

The Leona Fan Summer Vest is written in the following sizes:

XS/S (32–36 inch bust): approximately 400 yards
M/L (38–44 inch bust): approximately 480 yards
XL/2XL (46–52 inch bust): approximately 560 yards

Finished measurements include approximately 2–4 inches of positive ease, meaning the vest will be slightly larger than your actual bust measurement for a comfortable, relaxed fit. If you prefer a more fitted look, size down. If you like an oversized, flowy silhouette, size up or add a few extra fan repeats.

Stitch Glossary

Here are all the stitches you will use in this pattern. If you are comfortable with basic crochet stitches, you already know most of these.

Ch — chain
Sl st — slip stitch
Sc — single crochet
Dc — double crochet
Sk — skip
St(s) — stitch(es)
RS — right side
WS — wrong side
Rep — repeat

Fan Stitch: (5 dc, ch 1, 5 dc) all worked into the same stitch or space. This creates the signature fan shape.

Pattern Notes

This vest is worked in two flat panels — a front and a back — that are then seamed at the shoulders and partially down the sides. The armhole openings are created naturally by leaving a portion of the side seams unjoined. Ribbing along the bottom hem, armholes, and neckline is worked in slip stitch rib for a neat, stretchy finish.

The fan stitch is set up in a specific foundation that spaces the fans evenly. Each fan sits above a chain-1 space from the previous row, and the single crochet between fans anchors the pattern. Once you work the first two rows, the rhythm becomes intuitive and you will find yourself flying through the fabric.

Read through the entire pattern before starting so you have a clear picture of the construction. It is simpler than it looks on paper.

The Free Pattern: Leona Fan Summer Vest

Foundation and Setup Row

Start with a foundation chain. The number of chains you begin with must be a multiple of 11 plus 2.

For XS/S: chain 90
For M/L: chain 101
For XL/2XL: chain 112

Row 1 (Setup Row, WS): Sc in 2nd ch from hook and in each ch across. Turn.

You should have 89 (100, 111) sc stitches.

Row 2 (RS): Ch 3 (counts as first dc here and throughout). Skip next 4 sts. Work (5 dc, ch 1, 5 dc) into the next stitch. Skip 4 sts, sc into next st, skip 4 sts, work (5 dc, ch 1, 5 dc) into next st. Repeat from to across until 5 sts remain. Skip 4 sts, dc into last st. Turn.

Row 3 (WS): Ch 1, sc into first dc. Ch 4, sc into ch-1 space of next fan. Repeat from to across, ending with ch 4, sc into top of turning ch. Turn.

Row 4 (RS): Ch 3, work 5 dc into first ch-4 space. Sc into next sc, work (5 dc, ch 1, 5 dc) into next ch-4 space. Repeat from to across, ending with sc into last sc, 6 dc into last ch-4 space, dc into last sc. Turn.

Row 5 (WS): Ch 1, sc into first dc. Ch 4, sc into ch-1 space of fan. Repeat from to across, ending with ch 4, sc into top of turning ch. Turn.

Repeat Rows 4 and 5 until your panel measures approximately 13 (14, 15) inches from the foundation, or your desired length to the underarm. End with a Row 5.

This completes the back panel. Fasten off and set aside.

Work a second identical panel for the front.

Shoulder Shaping

For a clean shoulder line, you will work a few rows of flat fabric at the top of both panels before seaming. This creates a slightly firmer shoulder area and helps the vest sit properly.

After reaching your desired length on each panel, work 4 rows of sc across the full width of each panel. These rows form the shoulder band.

Lay your back panel flat on a surface. Place your front panel on top, with wrong sides facing each other. Using a yarn needle and a length of your project yarn, whipstitch or mattress stitch the shoulder seams together. Leave the center open for the neck opening. For all sizes, leave approximately 8–9 inches open at the center for the neckline. The remaining fabric on each side forms the shoulder connection.

Side Seams and Armhole Openings

With both panels joined at the shoulders, fold the vest so the side edges meet. Beginning at the bottom hem, seam upward approximately 8 (9, 10) inches. Stop here and leave the remainder open — this open portion becomes your armhole. Repeat on the other side.

Try the vest on at this point to check the fit. If you need a deeper or shallower armhole, adjust the seam length accordingly. The beauty of this construction method is that it is easy to customize before you commit to the final finish.

Finishing: Edging and Ribbing

Clean finishing makes a homemade garment look polished and professional. For the Leona Fan Summer Vest, we use a simple slip stitch rib worked into the edges.

Bottom Hem: Join yarn at any point along the bottom edge with a sl st. Ch 7. Sl st into the back loop only of the 2nd ch from hook and each ch across (6 sl sts). Sl st into the next 2 stitches along the garment edge. Turn. Sl st into back loop only of each st across the ribbing strip. Sl st into next 2 stitches along the edge. Repeat from to all the way around the bottom. When you reach your starting point, sl st the two short ends of the ribbing together to join. Fasten off and weave in ends.

Armhole Edges: Join yarn at the underarm point of each armhole. Work one round of sc evenly around the entire armhole opening, then work a second round as follows: sc in next st, skip 1 st. Repeat around for a slightly gathered, tidy edge. Fasten off. Repeat for the second armhole.

Neckline Edge: Join yarn at one shoulder seam. Work sc evenly around the entire neckline, placing extra sc at any corners to keep the edge lying flat. Work a second round of sl sts for a neat border. Fasten off.

Front Edges: If desired, work a single round of sc along both open front edges from hem to neckline. This is optional but gives the front a more finished look and prevents the edges from curling.

Weave in all remaining ends using your yarn needle, taking care to secure them well on the wrong side of the fabric.

Blocking the Leona Fan Summer Vest

Blocking is a step that many crocheters skip, but for a lace or open stitch garment, it is genuinely transformative. Blocking opens up the fan stitches, evens out the tension across the fabric, and gives the vest a drape and finish that is simply not achievable straight off the hook.

Fill a basin with cool water and add a small amount of wool wash or gentle soap. Submerge the vest completely and press it gently to saturate the fibers. Do not wring or twist. Lift the vest out and gently press excess water against the side of the basin, then roll it in a clean dry towel and press firmly to remove more moisture.

Lay the vest flat on a blocking mat or a clean carpeted surface covered with a towel. Use rust-proof pins to stretch and shape the fan stitches open, smoothing the fabric to your desired finished measurements. Allow it to dry completely before removing the pins — this may take 24 hours or more depending on your yarn and climate. Cotton in particular benefits enormously from a good block.

Yarn Substitution Ideas

The beauty of a free pattern like this one is that you can use whatever yarn speaks to you. Here are some ideas across different price points and yarn weights.

If you want to stay in the budget-friendly category, the Red Heart Soft Essentials in cotton is a reliable choice that blocks well and comes in a wide range of colors. For something a little more luxurious, Paintbox Simply DK Cotton or Lion Brand Feels Like Butta Lite offer incredible softness with beautiful stitch definition. If you are interested in a natural, sustainable fiber, Cascade Yarns Ultra Pima or any linen-cotton blend will give the vest a slightly more structured, earthy quality that ages beautifully over time.

For a boho aesthetic, try a variegated or ombre yarn that allows the color shifts to pool across the fan stitch pattern in unexpected ways. For a minimalist look, a classic white, cream, or sage solid will let the stitch texture speak for itself.

How to Style the Leona Fan Summer Vest

A crocheted summer vest is one of the most versatile pieces you can add to your warm-weather wardrobe. Here are a few ways to wear yours.

Over a simple white tank top and high-waisted denim shorts, the Leona vest becomes an effortlessly cool beach or festival look. Pair it with strappy sandals and layered necklaces and you have an outfit that works from a farmer’s market morning to a backyard evening gathering.

Worn over a flowy slip dress in a complementary color, the vest adds texture and dimension without adding weight or warmth. It is the kind of layering piece that actually makes sense in summer.

For a beach day, throw the vest over a bikini or one-piece swimsuit as a cover-up. The open fan stitches mean it dries quickly if it gets splashed, and it provides just enough coverage without trapping heat.

The vest also works beautifully as a layering piece during transitional weather — worn over a long-sleeve fitted top in early spring or late fall for a textured, artisan look that photographs especially well.

Tips for First-Time Garment Makers

If this is your first time crocheting a wearable garment, welcome to what will likely become a very enjoyable rabbit hole. A few pieces of advice to help you succeed:

Always, always swatch. It takes maybe twenty minutes and can save you hours of frogging. Gauge determines how the finished garment will fit, and it is worth the extra time upfront.

Measure yourself accurately before choosing your size. Look at the finished measurements listed in the pattern, not just the size label. A medium in one pattern might be a large in another, so focus on inches rather than letters.

Try the vest on periodically as you work, especially before seaming. This allows you to make small adjustments before anything is committed to a permanent join.

Do not skip blocking. It is worth saying again. Blocking will make your vest look like it came from a boutique rather than a craft session. The difference is that significant.

Final Thoughts

The Leona Fan Summer Vest is the kind of free crochet pattern that earns a permanent place in your project queue — something you return to season after season in new colorways, different yarn weights, and for new people in your life. It is fast enough to be satisfying, detailed enough to be engaging, and beautiful enough to wear with genuine pride.

Whether you are gifting it to someone special, donating it to a craft fair, or keeping it entirely for yourself (which you absolutely should do at least once), this vest is a celebration of what handmade can be: thoughtful, functional, and full of the quiet joy of making something beautiful from nothing more than yarn and a hook.

Happy crocheting, and have the most wonderful summer wearing something you made yourself.
