Crochet Bralette Pattern: Free Step-by-Step Instructions for Every Skill Level

There is something deeply satisfying about wearing a piece of clothing you made with your own hands. A crochet bralette sits at the intersection of functional and beautiful — it’s wearable art that you can customize to your exact measurements, preferred yarn, and personal style. Whether you’re a confident crocheter looking for a new challenge or an intermediate maker ready to step up from dishcloths and scarves, this free crochet bralette pattern will walk you through everything you need to know from materials to finishing touches.

This pattern is designed to be approachable without being oversimplified. You’ll find detailed explanations for each step, sizing guidance, and tips for customizing the fit so the finished piece works for your body rather than against it.

What You’ll Need Before You Start

Getting your materials together before you begin makes the whole process much smoother. Here’s what you’ll want to have on hand.

Yarn: For a bralette, cotton yarn is the gold standard. It’s breathable, soft against skin, and holds its shape well after washing. A size 2 (fine) or size 3 (light) cotton yarn works beautifully for this project. Some popular choices are Lion Brand 24/7 Cotton, Paintbox Simply DK Cotton, or Drops Safran. You’ll need approximately 200–350 yards depending on your size and how you adapt the pattern.

Hook: A 3.5mm (E/4) or 4mm (G/6) crochet hook is ideal. If you tend to crochet tightly, go up half a size. If you crochet loosely, go down half a size.

Notions: You’ll need a yarn needle for weaving in ends, scissors, stitch markers, a measuring tape, and about one yard of thin elastic cord or a bra extender if you want added support and structure at the band.

Gauge: For this pattern, you’re aiming for approximately 18 stitches and 20 rows per 4 inches in half double crochet using a 4mm hook. Always swatch before you begin, especially for a wearable item. A gauge that’s off by even half a stitch per inch can change the fit significantly across the full width of the piece.

Understanding the Sizing

This pattern is written for sizes XS through XL with the following approximate underbust measurements as a guide.

XS fits an underbust of 26–28 inches. S fits 28–30 inches. M fits 30–33 inches. L fits 33–36 inches. XL fits 36–39 inches.

The cups in this pattern are designed to offer a relaxed, bralette-style fit rather than a structured underwire fit. If you have a fuller bust, you may want to add one or two extra rows to each cup or increase the cup starting chain by two stitches per size up you go. More on that in the cup section below.

Throughout the pattern, instructions for different sizes are written in order: XS (S, M, L, XL). Where only one number appears, it applies to all sizes.

Pattern Instructions

Part One: The Band

The band is worked flat in rows and then seamed, or you can work it in the round if you prefer a seamless finish. The instructions below are written for flat construction with a seam at the center back.

Foundation chain: Chain 118 (126, 138, 150, 162). This should measure approximately 24 (26, 28, 30, 32) inches.

Row 1 (RS): Starting in the second chain from the hook, sc across. You should have 117 (125, 137, 149, 161) stitches. Turn.

Row 2 (WS): Ch 1, sc in each stitch across. Turn.

Row 3: Ch 1, sc in each stitch across. Turn.

Row 4: Ch 2, hdc in each stitch across. Turn.

Row 5: Ch 2, hdc in each stitch across. Turn.

Row 6: Ch 2, hdc in each stitch across. Turn.

Row 7: Ch 1, sc in each stitch across. Fasten off, leaving a long tail for seaming.

The band should measure approximately 2.5 inches tall. Fold the piece so the short ends meet, wrong sides together, and seam using a whip stitch or mattress stitch through the back loops only. This creates the center back join. Weave in your ends.

Adding the elastic (optional but recommended): Cut a piece of elastic that fits snugly but comfortably around your underbust. Overlap the ends by about half an inch and stitch them together. Using your yarn needle and a length of matching yarn, tack the elastic to the inside of the band using simple whip stitches. Space your tacking stitches about half an inch apart so the elastic sits flat and doesn’t bunch.

Part Two: The Cups

The cups are worked separately and then attached to the band. Each cup is worked in rows, increasing at the sides to form a gently rounded shape.

Making Cup One (make 2):

Foundation chain: Chain 26 (28, 30, 32, 34).

Row 1 (RS): Starting in the second chain from the hook, hdc in each chain across. You will have 25 (27, 29, 31, 33) stitches. Turn.

Row 2: Ch 2, 2 hdc in the first stitch (increase made), hdc in each stitch to the last stitch, 2 hdc in the last stitch (increase made). You’ll now have 27 (29, 31, 33, 35) stitches. Turn.

Row 3: Ch 2, hdc in each stitch across. Turn.

Row 4: Repeat Row 2. You’ll now have 29 (31, 33, 35, 37) stitches. Turn.

Row 5: Ch 2, hdc in each stitch across. Turn.

Row 6: Repeat Row 2. You’ll now have 31 (33, 35, 37, 39) stitches. Turn.

Rows 7–8: Ch 2, hdc in each stitch across. Turn.

Row 9: Repeat Row 2. You’ll now have 33 (35, 37, 39, 41) stitches. Turn.

Rows 10–11: Ch 2, hdc in each stitch across. Turn.

For sizes XS and S, you can stop here. For sizes M, L, and XL, continue with two more increase rows as follows.

Row 12 (M, L, XL only): Repeat Row 2. 39 (41, 43) stitches. Turn.

Row 13 (M, L, XL only): Ch 2, hdc in each stitch across. Turn.

Shaping the top of the cup:

Now you’ll shape the upper edge of the cup with decreases to create that soft curved look.

Next row: Ch 1, sc in the first stitch, hdc in the next 2 stitches, dc in the stitches across to the last 3 stitches, hdc in the next 2 stitches, sc in the last stitch. Turn.

Next row: Ch 1, sc in the first stitch, hdc2tog, hdc across to the last 3 stitches, hdc2tog, sc in the last stitch. Turn.

Next row: Ch 1, sc in each stitch across. Fasten off, leaving a long tail.

Repeat for the second cup. Hold the cups side by side with right sides facing up. They should be mirror images of each other.

Part Three: Attaching the Cups to the Band

This is the step that can feel intimidating for first-timers, but it’s much more forgiving than it looks. The key is to take your time and use stitch markers.

Lay the band flat with the right side facing you. Identify the front center of the band. Mark this point with a stitch marker. The band should be divided roughly into thirds: left third, center third, and right third.

Place Cup One on the left third of the band, centered within that section. Use stitch markers to pin it in place, making sure the bottom edge of the cup aligns with the top edge of the band. Using the long tail you left on the cup and a yarn needle, whip stitch along the bottom edge of the cup to attach it to the band. Work slowly and try to keep your tension even. Fasten off and weave in ends.

Repeat for Cup Two on the right third of the band.

The center third of the band (the area between the two cups) forms the underbust center front panel. You can leave this plain or add a decorative element like a small sewn-on button, a crocheted bow, or a cluster of surface slip stitches for texture.

Part Four: The Straps

The straps give this bralette its signature look. You’ll make two straps — one for each cup — and they can be styled as straight shoulder straps, a halter top, or a crisscross style across the back.

For standard shoulder straps:

Using your hook and yarn, join yarn to the upper outer corner of Cup One.

Foundation: Ch 2, then work a single crochet strap as follows: ch 1, turn, sc in the second chain from the hook, ch 1, turn. Continue working back and forth in this I-cord-style flat strap until the strap measures 12 (12.5, 13, 13.5, 14) inches or your desired length.

A slightly faster method that gives a lovely, denser strap: work a flat strap by chaining 4 and working single crochet rows across all 4 stitches, turning each row, until you reach your desired length.

Fasten off, leaving a long tail. Try the bralette on (or measure against yourself) to confirm strap length before attaching the other end. Sew the end of the strap to the top inner corner of the same cup, or to the band at the back depending on your preferred strap style.

For a halter style: Work the strap much longer — approximately 20–22 inches — and instead of attaching it to the band, you’ll tie it at the back of the neck or at the center back.

For a crisscross back: Make each strap about 18 inches long and sew the end of the left strap to the right side of the back band, and vice versa.

Part Five: The Finishing Edge

A good finishing edge elevates the whole piece and gives it that polished, professional look.

Starting at the center back seam, join yarn to the top edge of the band and work a single crochet edging all the way around the upper perimeter of the bralette — across the band, up around each cup, and back down to where you started. Work 1 sc into each stitch and 1 sc into each row end as you travel around curved edges. When you reach corners, work 3 sc into the same stitch to keep the edge from pulling.

Slip stitch to join. Fasten off and weave in all remaining ends.

For a picot edge (optional): Instead of plain single crochet, work (sc, ch 3, sl st into the first of those 3 chains) into every third stitch as you travel around. This creates a delicate, scalloped look that suits the feminine feel of the bralette beautifully.

Tips for Getting the Best Fit

Fit is the whole game with a bralette, and a little planning goes a long way.

Swatch honestly. It’s tempting to skip it, but swatching in the round or flat depending on how you’re working the piece gives you real information about how your gauge behaves. Wash and block your swatch before measuring — cotton yarn can relax or tighten depending on the fiber content and how you treat it.

Measure twice. Take your underbust measurement (directly under your bust, pulled snug), your bust measurement (at the fullest part), and the difference between them. If the difference is 1 inch, you’re roughly an A cup. 2 inches is a B, 3 inches is a C, and so on. For anything beyond a B cup, plan to add extra rows to your cup construction.

Block before wearing. Cotton responds beautifully to wet blocking. Soak the finished bralette in cool water, gently squeeze out excess moisture, and pin it flat to dry. This evens out tension and gives the piece a much more refined appearance.

Try it on mid-project. After attaching the cups to the band but before making the straps, try the bralette on if you can. This lets you assess cup placement and band fit before committing to strap length.

Washing and Care

Because this bralette will sit close to your skin, wash it regularly and gently. Hand washing in cool water with a small amount of gentle soap is ideal. If machine washing, use a mesh laundry bag, cold water, and a delicate cycle. Lay flat to dry rather than hanging, which can stretch the fabric. Avoid high heat in the dryer, which can shrink and warp cotton yarn.

Ways to Customize This Pattern

One of the best things about making your own bralette is how easy it is to make it yours.

You can change the yarn weight to create a different feel. A fingering weight yarn on a smaller hook produces a very fine, delicate fabric. A worsted weight yarn gives a thicker, more supportive structure. Just remember to adjust your stitch count accordingly.

You can incorporate colorwork. A simple stripe pattern in the band or alternating colors in each cup adds personality without requiring any complex techniques.

You can swap the stitch. The cups in this pattern use half double crochet, but you could experiment with a mesh stitch, a shell stitch, or a cluster stitch for texture. Just keep your swatch so you can compare how the new stitch changes your gauge.

You can add underwire casing. If you want more support, sew a thin fabric channel along the inside bottom edge of each cup and thread a soft bra underwire through it. This transforms the bralette into something with real structure.

A Final Word

Making a crochet bralette for the first time feels like a big step, and it is — but it’s also one of the most rewarding projects you can take on. Every step of this pattern builds on the last, and by the time you’re weaving in your final ends, you’ll have a wearable piece that fits your body and reflects your craft.

Share your finished makes if you decide to post them — the crochet community is endlessly enthusiastic and generous with encouragement. If you adapt this pattern or find a combination that works especially well for your shape, note it down so you can repeat it for future versions.

Happy crocheting.
