Want a handmade bikini that looks like it came from a fancy boutique instead of your craft room? This lavender set delivers exactly that. Soft triangle cups with scalloped edges, tiny layered flowers, and comfy boy-short bottoms that actually stay put. Grab your hook and let’s make something pretty for summer.
What This Cute Set Looks Like
You get a two-piece crochet bikini in soft lavender. The top has classic triangle cups that grow wider with simple increases. Each cup finishes with a pretty shell-stitch scallop edge that waves along the sides. Crocheted cords tie at the neck and around the back so you can adjust the fit perfectly.
The bottoms start with a stretchy ribbed waistband that hugs without digging in. Then the body works down in rounds before you shape the crotch and open the legs. Side ties add extra adjustability and a sweet touch. Five small layered flower appliques in purple and white scatter across both pieces for that final charm.
It works for pool days, beach walks, or just those summer photos you want to post. The whole set feels intentional, not homemade-awkward.
Skill Level and Time You’ll Need
This pattern sits at intermediate level. You should already know how to work in rows and rounds, increase and decrease for shaping, work in the front loop only for ribbing, make a magic ring, join rounds, and do a simple shell stitch.
Don’t panic if that list feels long. Most of the fabric uses basic single crochet. The flowers are the fiddliest part because they’re tiny, but you can skip them if you want something simpler.
Time estimate looks like this:
- Top: about 6 to 9 hours
- Bottoms: about 8 to 12 hours
- Five flowers: about 1 to 2 hours
Total lands around 15 to 23 hours depending on your speed. Break it into evening sessions and it feels totally doable.
Finished Size and Materials
The top is one size and fully adjustable with the ties. Each cup measures roughly 5 inches wide at the base and 4.5 inches tall. Band ties run about 18 inches each side. Neck ties run about 14 inches each.
Bottoms are written for US Small to Medium. Waist sits around 26 to 30 inches with the ties. Hips measure about 34 to 36 inches. Rise from waistband to crotch is about 8 inches, and the inseam is short at 2 inches.
Yarn
- About 500 yards of worsted weight (category 4) in main lavender
- About 15 yards each of two contrast colors for flowers (medium purple and pale white or very light lavender)
Good choices include soft acrylics that show stitch definition clearly. If you plan to swim in it, pick a cotton or cotton blend and go up one hook size because cotton is denser.
Hooks
- US G-6 (4.0 mm) for the main fabric
- US F-5 (3.75 mm) for flowers and edging details
Notions
Yarn needle, scissors, at least 6 stitch markers, measuring tape. Optional small padding for the cups if you want extra shape.
Gauge
With the 4.0 mm hook in single crochet: 16 stitches and 18 rows equal 4 inches. Make a small swatch and measure the center. Adjust your hook if needed. Gauge matters most for the bottoms so they fit the waist and hips properly.
Abbreviations and Special Stitches
Here is every abbreviation you’ll meet, written simply:
- ch = chain
- sl st = slip stitch
- sc = single crochet
- hdc = half double crochet
- dc = double crochet
- tr = treble crochet
- inc = increase (2 sc in same stitch)
- dec = decrease (sc2tog)
- FLO = front loop only
- BLO = back loop only
- sk = skip
- sp = space
- st / sts = stitch / stitches
- RS / WS = right side / wrong side
- MR = magic ring
- rnd = round
- rep = repeat
- rem = remaining
- beg = beginning
- pm = place marker
- sm = slip marker
Shell Stitch
Work 5 dc all into the same stitch or space. That makes one shell.
Scallop Edging
- Join yarn at the starting corner.
- Ch 1, work 1 sc in the first stitch.
- Skip 1 stitch.
- Work 5 dc (one shell) into the next stitch.
- Skip 1 stitch.
- Work 1 sc into the next stitch.
- Repeat steps 3–6 across, ending with 1 sc.
- Fasten off.
- The edge needs a stitch count that is a multiple of 4 plus 1 so the scallops start and end neatly with a single crochet.
Crocheted Cord / Chain Tie
Make a slip knot, chain to the length you need, then slip stitch tightly back through each chain. This makes a firm round cord. The slip-stitched version holds up better than a plain chain.
Small Flower Applique (Make 5)
Each flower has two layers.
Layer 1 (back petals, medium purple):
- Make a magic ring.
- Ch 1, work 6 sc into the ring. Pull closed.
- Working in a continuous spiral, (ch 3, sl st into same st, sl st into next st) 6 times.
- Fasten off leaving a tail.
Layer 2 (front petals, pale white or light lavender):
- Make a magic ring.
- Ch 1, work 5 sc into the ring. Pull closed.
- (ch 2, sl st into same st, sl st into next st) 5 times.
- Fasten off leaving a tail.
Stack the small white flower on the larger purple one so the petals interleave. Sew them together through the center, then sew the finished flower onto the garment.
Bikini Top Pattern
Triangle Cups (Make 2)
Work each cup in rows from the base upward. Increases at both edges create the triangle shape.
With G-6 hook and main color:
Foundation: Ch 4.
Row 1 (RS): Sc in 2nd ch from hook, sc in next 2 ch. Turn. (3 sc)
Row 2 (WS): Ch 1, inc in first st, sc to last st, inc in last st. Turn. (5 sc)
Row 3: Ch 1, inc, sc across, inc. Turn. (7 sc)
Row 4: Ch 1, inc, sc across, inc. Turn. (9 sc)
Row 5: Ch 1, inc, sc across, inc. Turn. (11 sc)
Row 6: Ch 1, inc, sc across, inc. Turn. (13 sc)
Row 7: Ch 1, inc, sc across, inc. Turn. (15 sc)Row 8: Ch 1, inc, sc across, inc. Turn. (17 sc)
Row 9: Ch 1, inc, sc across, inc. Turn. (19 sc)
Row 10: Ch 1, inc, sc across, inc. Turn. (21 sc)
Row 11: Ch 1, inc, sc across, inc. Turn. (23 sc)
Row 12: Ch 1, inc, sc across, inc. Turn. (25 sc)
Row 13: Ch 1, inc, sc across, inc. Turn. (27 sc)
Row 14: Ch 1, inc, sc across, inc. Turn. (29 sc)
Row 15: Ch 1, inc, sc across, inc. Turn. (31 sc)
Row 16: Ch 1, sc across all sts. Turn. (31 sc)
Each cup should measure about 4.5 inches tall and 7.75 inches wide at the base. Make the second cup the same way.
Joining the Cups
Hold both cups with RS facing you. Join yarn at the bottom inner corner of the left cup. Working through both layers, slip stitch the inner edges together for about 8 row ends (halfway up). Fasten off. Or use a whip stitch on the wrong side for a cleaner join.
Scallop Edging on Cups
Work the scallops only on the two diagonal outer edges of each cup. The base stays plain. Each outer edge has 15 row ends. Work 1 sc into each row end, but put 2 sc into row ends 4 and 12 so you reach 17 stitches. Then work the scallop pattern across those 17 stitches (4 shells and 5 sc). At the top point, work 1 sc, 5 dc into the tip, then 1 sc to round it nicely.
Neck Ties (Make 2)
Ch 56 (about 14 inches). Slip stitch tightly back through each chain. Attach one cord to the tip of each cup.
Band Ties (Make 4)
Ch 72 (about 18 inches). Slip stitch tightly back. Attach one tie to each lower outer corner of the cups.
Boy-Short Bottoms Pattern
Ribbed Waistband
With G-6 hook and main color, ch 13.
Row 1: Sc in 2nd ch from hook and each ch across. Turn. (12 sc)
Row 2: Ch 1, sc in FLO of each st across. Turn. (12 sc)
Repeat Row 2 until the strip measures 26 inches (about 117 rows). Seam the short ends together with slip stitches or whip stitch. The seam sits at center back.
Waistband Top Edging
With RS facing, join yarn at the back seam on the top edge. Ch 1, sc evenly around (1 sc per row end), working 116 sc total. Join with slip stitch. Fasten off.
Body from Waistband Bottom
Turn the tube so the unworked edge faces up. Join yarn at the back seam.
Rnd 1: Ch 1, sc evenly around (116 sc). Join.
Rnds 2–16: Ch 1, sc in each st around. Join. (116 sc)
Crotch Shaping
Mark stitch 1 (center back) and stitch 59 (center front).
Front panel (58 sts):
Row 1: Join at stitch 59, ch 1, sc across the 58 front sts. Turn.
Rows 2–9: Ch 1, dec, sc to last 2 sts, dec. Turn. Continue until 42 sc remain. Fasten off.
Back panel (58 sts): Join at stitch 1 and work the same decrease sequence until 42 sc remain. Do not fasten off.
Rejoining for Leg Openings
Fold so the front and back crotch edges meet. Slip stitch the first front and back stitches together, sc across the front panel, slip stitch the last stitches together, then sc across the back. Join into a round of 84 sc. Work two more rounds of sc.
Leg Opening Edging
With F-5 hook, work one round of single crochet evenly around each leg opening (about 21 sc). Adjust as needed so it sits smoothly.
Side Ties for Bottoms (Make 4)
Ch 32, slip stitch back tightly. Attach one pair to each side of the waistband midway between center front and center back.
Flower Placement
Sew one flower at the center front of the top where the cups meet. Place one on the upper left and one on the upper right of the cups along the scallops. Put one or two on the center front of the bottoms waistband. Move them around until you like the look.
Size Tweaks, Finishing, and Care
Want smaller cups? Stop at Row 12. For larger cups keep going to Row 18 or 20.
Make the waistband strip 2 inches shorter than your actual waist for a snug fit, or 4–6 inches shorter if you want the ties to do more work.
Add or subtract 16 stitches in the body rounds for every 4 inches of hip difference.
Add or subtract body rounds to change the rise. Each round adds about 0.22 inches.
Weave in every end securely. Wet block both pieces in cool water for 10–15 minutes. Squeeze gently, roll in a towel, then pin flat. Shape the cups into rounded triangles and open the scallops. Let them dry completely (at least 24 hours). Sew the flowers on after blocking.
For acrylic yarn, machine wash gentle cycle in cool water. Hand wash cotton blends. No bleach or softener. Lay flat to dry away from heat and sun. Store folded, not hung.
