3. US Crochet Abbreviations & Stitch Meanings

ch: Chain stitch
sl st: Slip stitch
sc: Single crochet
hdc: Half double crochet
dc: Double crochet
st(s): Stitch or stitches
sp: Space
ch-sp: Chain space
Shell: 5 double crochets worked into the exact same stitch to create a rounded scallop
BLO: Back loop only
FO: Fasten off

Special Technique: Arch Peak Shaping `[2 dc, ch 1, 2 dc]`

When working amigurumi or garment cups, working two double crochets, a chain, and two more double crochets into the very top turning chain of the foundation strip expands the cup outward and upward simultaneously. This forms a gentle, natural 3D cone curve that fits comfortably over the bust.

4. Skills to Know Before Starting

Working Across Both Sides of a Center Chain: Start by working down the foundation chain, make your peak increases at the apex, and continue working along the unworked bottom loops of the same chain.
Color Changes on Garment Ridges: Complete the final yarn-over of the last stitch in a row with your new color to keep transitions clean and crisp.
Checking Gauge for Wearable Fit: Cotton yarn has minimal elasticity, so maintaining firm, consistent tension ensures the bralette holds its shape throughout the day without stretching out.

5. Understanding the Bralette Anatomy

This bralette is assembled from four integrated sections:

Bust Cups (Make 2): Crocheted from the vertical center outward using concentric bands of terracotta, sage green, and cream.
Center Front Eyelet Border: A neat column of chain loops worked along the inner cup edges to host the corset lace-up tie and tiny daisy accents.
Ribbed Underbust Band: Attached directly to the bottom edges of both cups, providing firm structure and torso support.
Shell Edging & Straps: Scalloped shell borders framing the top ridges and bottom band, finished with twisted cord ties and playful tassel ends.

6. Sizing and Calibration Guide

Use these starting foundation chains to achieve your exact cup size:

Extra Small / Small (Cup A): Chain 11 to start (approx. 5 inches wide and tall).
Small / Medium (Cup B / Small C – Model Size): Chain 13 to start (approx. 6 inches wide and tall).
Large (Cup C / D): Chain 15 to start (approx. 7 inches wide and tall).
Extra Large (Cup DD+): Chain 17 to start (approx. 8 inches wide and tall), adding 2 extra outer rounds.

Measure from the bottom fold of the bust to the center apex to determine your ideal starting chain height.

7. Complete Step-by-Step Crochet Pattern

Part A: The Molded Bust Cups (Make 2 Alike)

Starting in Color A (Terracotta):

Foundation Chain: Ch 14 (for Small/Medium).
Round 1: Starting in the 3rd chain from the hook, work 1 dc in each of the next 11 chains. In the final chain space, work [2 dc, ch 1, 2 dc] to form the peak. Working down the opposite side of the foundation chain loops, work 1 dc in each of the next 11 chains [26 dc total, 1 ch-1 peak space]. Ch 2, turn.
Round 2: Work 1 dc in each st up the side to the peak space (13 dc). In the peak ch-1 space, work [2 dc, ch 1, 2 dc]. Work 1 dc in each st down the opposite side (13 dc) [30 dc total]. Ch 2, turn.
Rounds 3–4 (2 rounds): Repeat Round 2 in Terracotta, working 1 dc in each st along the sides and [2 dc, ch 1, 2 dc] into the peak space. At the end of Round 4, switch to Color B (Sage Green) on the final yarn-over. Ch 2, turn.

Switching to Color B (Sage Green):

Round 5: In Sage Green, work 1 dc in each st to peak, work [2 dc, ch 1, 2 dc] in peak space, work 1 dc in each st down the opposite side. Ch 2, turn.
Round 6: Repeat Round 5 in Sage Green. Switch to Color C (Cream) on the final yarn-over. Ch 2, turn.

Switching to Color C (Cream):

Round 7: In Cream, work 1 dc in each st to peak, [2 dc, ch 1, 2 dc] in peak space, work 1 dc in each st down the other side. Switch to Color A (Terracotta) on the final yarn-over. Ch 2, turn.

Finishing with Color A (Terracotta):

Round 8: In Terracotta, work 1 dc in each st to peak, [2 dc, ch 1, 2 dc] in peak space, work 1 dc in each st down the side. Do not fasten off; rotate to work across the bottom edge.
Base Round: Work 1 row of sc evenly across the raw bottom edge of the cup (placing roughly 2 sc per double crochet row post). Fasten off. Repeat for the second cup.

Part B: Center Front Eyelet Edge & Mini Daisy Appliques

Eyelet Loops: Reattach Cream yarn at the bottom inner edge of one cup. Work along the vertical inner center: *1 sc, ch 2, skip 1 st; repeat from * up the inner edge to create 4 or 5 clean lacing eyelets. Fasten off and repeat on the opposite cup’s inner edge.
Mini Daisies (Make 4 to 6):
- With Cream yarn: In a MR, work *(sl st, ch 2, 2 dc, ch 2, sl st) into the ring; repeat from * 5 times to form 5 petals.
- Pull ring tight and fasten off, leaving an 8-inch tail. Sew these dainty flowers along the eyelet border edge.

Part C: Supportive Underbust Band

Joining Cups: Lay both cups flat side-by-side with inner eyelet edges aligned.
Row 1 (Band Foundation): Join Color A (Terracotta) at the outer bottom corner of the right cup. Ch 2, work dc evenly across the bottom of the right cup, chain 2 across the central gap, and continue working dc evenly across the bottom of the left cup. Ch 2, turn.
Rows 2–3 (Terracotta): Work 1 dc in each st across. On final st of Row 3, switch to Color B (Sage Green). Ch 2, turn.
Rows 4–5 (Sage Green): Work 1 dc in each st across. Switch to Color C (Cream). Ch 2, turn.
Row 6 (Cream): Work 1 dc in each st across. Switch to Color A (Terracotta). Ch 2, turn.
Row 7 (Terracotta): Work 1 dc in each st across. Fasten off.

Part D: Scalloped Shell Trim

Top Cup Trim (Terracotta / Cream): Join yarn at the outer bottom corner of the cup arch. *Skip 1 st, work 5 dc in the next st (shell made), skip 1 st, sl st in next st; repeat from * up the outer edge, over the peak, and down the inner edge.
Bottom Band Trim: Join Color C (Cream) at the bottom corner of the underbust band. Work the identical shell sequence [skip 1, 5 dc, skip 1, sl st] across the entire lower hem. Fasten off.

Part E: Straps, Corset Ties & Tassels

Halter Neck Straps (Make 2): Join Color A (Terracotta) to the peak of each cup. Chain 85 to 100 stitches (approx. 20 inches). Starting in 2nd ch from hook, work sl st in each ch back to the peak. Fasten off securely.
Corset Front Lacing Tie: With Color A or double-stranded Cream yarn, make a sturdy chain of 140 stitches. Weave the cord through the front eyelet loops in a crisscross lace-up pattern.
Back Ties (Make 2): Attach yarn to the outer edges of the underbust band, chain 90 stitches, and slip stitch back.
Tassels: Cut twelve 6-inch strands of Sage Green and Terracotta yarn. Fold in half, slip through the cord ends, wrap, and knot tightly to create playful fringe tassels.

11. Troubleshooting Common Problems

The cups look flat instead of curved: Ensure you work [2 dc, ch 1, 2 dc] into the peak space on every round. These increases create the natural 3D cup curvature.
The underbust band bunches or flares: If the band flares, your foundation row contains too many stitches across the cup bases. Place exactly 2 single crochets around each double crochet side post.
The top stretches out after wear: Cotton yarn can relax slightly over time. Simply pull the back and front corset ties tighter for a renewed custom fit.
The stitches look see-through: Drop down half a hook size (e.g., from 4.0 mm to 3.5 mm) to produce a tightly woven, opaque fabric.

12. Frequently Asked Questions

1. Can I insert bra cups or padding inside this top?

Yes. You can easily hand-sew lightweight fabric bra cup inserts onto the inside wrong side of the cups with matching thread for added modesty and support.

2. Is acrylic yarn suitable for this top?

100% cotton, bamboo, or linen blends are much better suited for wearables. Acrylic retains heat, does not breathe well in warm weather, and tends to stretch out permanently under tension.

3. How do I wash and care for this crochet top?

Hand wash in cool water using mild detergent. Gently press out excess moisture between clean towels without wringing, then lay flat to dry.

4. Can I make this top longer into a full tank top?

Yes. Continue adding rows to the underbust band until you achieve your preferred waist or hip length, then finish with the scalloped shell border along the bottom hem.

This boho crochet bralette top combines thoughtful tailoring with relaxed festival style. Its adjustable ties, comfortable cotton feel, and warm earth-toned stripes make it a versatile summer staple that you’ll reach for season after season.
