Cream Bridal Shell Bikini Crochet Free Pattern

A handmade bridal bikini makes a truly thoughtful gift for a bride-to-be, or a special keepsake you create for yourself. This two-piece set features sculpted shell cups with raised texture, scalloped edges throughout, layered decorative hip shells, and optional pearl accents. The stitches used include single crochet (sc), double crochet (dc), and front post double crochet (fpdc) for the signature shell ribs. The pattern works up in approximately 12 to 18 hours, making it a rewarding project for an intermediate to advanced crocheter looking to create something elegant and memorable.

About This Bridal Shell Bikini Crochet Pattern

This romantic crochet bikini set combines several techniques to achieve its polished bridal look. The top features two shaped shell cups worked from an adjustable ring outward, creating the distinctive radiating shell texture you see in the photographs. These cups attach to a narrow underbust band with adjustable straps and back ties.

The high-waist bottom is constructed from separate front and back panels, shaped from the crotch upward with gradual increases. Once seamed, you add a waistband with elastic casing for a secure fit, scalloped leg edgings, and six small decorative shell motifs at the hips.

The soft ivory cotton yarn creates that classic bridal aesthetic, while the optional pearl beads add a touch of elegance to the cups and hip shells.

Skill Level and Time Estimate

Skill level: Intermediate to advanced. You will work shaped rows, front post texture, scalloped edging, joining pieces, elastic casing, and decorative motif placement.

Time estimate: 12 to 18 hours, plus blocking and drying time.

Finished Size

Cup dimensions: Approximately 6.75 inches (17 cm) tall and 7.5 inches (19 cm) wide after blocking.

Bottom waist: Approximately 21 inches (53.5 cm) unstretched, comfortably fitting 26 to 32 inches (66 to 81 cm) with elastic and side shaping.

Bottom rise: Approximately 9.5 inches (24 cm).

Intended ease: The bottom uses negative ease at the waist with elastic. The cup has light structure and adjustable straps. I recommend swatching and matching gauge before starting to ensure a wearable fit.

Materials Needed

Gathering your supplies before you begin makes the process much smoother. Here is everything you need:

Yarn:

Fingering weight or size 2 sport cotton blend

520 to 650 yards (475 to 595 m) in ivory or cream

Yarn Suggestions:

Scheepjes Catona 4 ply cotton: Crisp stitches and strong shell definition

Hobbii Friends Cotton 8/4: Smooth matte finish with many cream shades

YarnArt Begonia: Slightly lustrous cotton for a dressier bridal texture

Substitution note: Choose firm cotton or cotton-bamboo. Avoid very stretchy acrylics unless you line the pieces.

Hook:

2.75 mm crochet hook, or size needed for gauge

Notions:

Tapestry needle

Stitch markers

Pins

Removable markers

Scissors

3/8 inch (1 cm) swimwear elastic: approximately 1 yard (1 m)

Optional:

Six 6 mm pearl beads

Hook-and-eye or small clasp

Lining fabric for additional coverage

Gauge

24 sc and 26 rows = 4 inches (10 cm) in blocked single crochet.

20 dc and 10 dc rows = 4 inches (10 cm) in blocked shell cup fabric.

Matching both stitch and row gauge is important for a wearable fit. Take the time to swatch before diving into the main pieces.

Abbreviations (US Terms)

Before we begin, let me walk you through every stitch abbreviation you will encounter:

ch = chain: Wrap yarn over hook and pull through the loop on your hook

sl st = slip stitch: Insert hook, yarn over, pull through stitch and loop on hook in one motion

sc = single crochet: Insert hook, yarn over, pull up a loop, yarn over, pull through both loops

hdc = half double crochet: Yarn over, insert hook, pull up a loop, yarn over, pull through all three loops

dc = double crochet: Yarn over, insert hook, pull up a loop, yarn over, pull through two loops, yarn over, pull through remaining two loops

fpdc = front post double crochet: Yarn over, insert hook from front to back to front around the post of the stitch below, yarn over and pull up a loop, then finish as a dc. This raised post creates the shell ribs.

st(s) = stitch(es)

RS/WS = right side / wrong side

rep = repeat

Special Stitches Explained

Scallop: Work 5 dc in the same stitch, skip 2 sts, sl st in next st, skip 2 sts. A scallop uses 6 base stitches.

Small picot: Ch 3, sl st in the first ch made. Use picots at cup points and strap edges if desired.

Pattern Notes

Before you begin crocheting, please review these important notes:

Ch-1 does not count as a stitch. Ch-3 counts as the first dc on shell cup rows.

Place 8 removable markers on the shell cup ridge positions after Row 2. Move markers up each row.

For left-handed makers, work the same instructions. Your shell ribs will lean in the opposite direction. Mirror placement when sewing cups and hip shells.

UK note: US sc = UK dc; US dc = UK tr.

This pattern is designed to help you create a similar crochet project, but individual results may vary depending on your yarn, tension, hook size, and finishing technique. You may need to make small adjustments to achieve the closest possible result to the finished project shown.

Shell Cups (Make 2)

Work flat in turned rows. Keep the RS of the raised ribs facing you on odd-numbered rows.

Row 1: Make adjustable ring. Ch 3, work 7 dc in ring. Turn. (8 dc)

Row 2: Ch 3, dc in same st, 2 dc in each st across. Turn. Place 8 ridge markers evenly. (16 dc)

Row 3: Ch 3, fpdc in marked st, 2 dc in next st; rep from across, moving markers to fpdc. Turn. (24 dc)

Row 4: Ch 3, fpdc in marked st, dc in next st, 2 dc in next st; rep from across. Turn. (32 dc)

Row 5: Ch 3, fpdc in marked st, dc in next 2 sts, 2 dc in next st; rep from across. Turn. (40 dc)

Row 6: Ch 3, fpdc in marked st, dc in next 3 sts, 2 dc in next st; rep from across. Turn. (48 dc)

Row 7: Ch 3, fpdc in marked st, dc in next 4 sts, 2 dc in next st; rep from across. Turn. (56 dc)

Row 8: Ch 3, fpdc in marked st, dc in next 5 sts, 2 dc in next st; rep from across. Fasten off. (64 dc)

Cup Edge

Join yarn at one lower corner. Work 1 sc into each row end up the side, 3 sc in top center point, 1 sc into each row end down the other side, then 64 sc across the lower curved edge. Sl st to first sc.

Work scallops across the lower curved edge only: *skip 2, 5 dc in next, skip 2, sl st in next; rep across, easing the final scallop as needed. Fasten off.

Cup shaping tip: Steam lightly and pinch the lower center inward by about 0.5 inches (1.25 cm) before sewing to the band. This makes the cup curve toward the body for a more natural fit.

Checkpoint

After cup Row 8, each cup has 64 dc and measures about 6.75 inches (17 cm) tall before edging. If your measurements differ significantly, check your gauge.

Underbust Front Band

Row 1: Ch 79. Sc in 2nd ch from hook and each ch across. Turn. (78 sc)

Rows 2-5: Ch 1, sc across. Turn after each row. (78 sc)

Row 6: Ch 1, sc in first 38 sts, ch 2, skip 2 center sts, sc in final 38 sts. Turn. (76 sc + ch-2 space)

Row 7: Ch 1, sc in each sc and 2 sc in ch-2 space. Fasten off. (78 sc)

Attach Cups

Place cups side by side on the band with the lower curved edge centered. Leave about 1 inch (2.5 cm) between inner cup points.

Whipstitch through the back loops of the cup edging and the top row of the band. Keep shell ribs facing outward.

Add one pearl to each cup center and one to each lower cup point, securing firmly.

Straps and Back Ties

For each shoulder strap: Join yarn at the upper cup point, ch 72, turn, sc in 2nd ch from hook and across, sl st to cup point. Work one scalloped edge along the outer side: *skip 2, 5 dc in next, skip 2, sl st in next; repeat to the end.

For each back tie: Join at band end, ch 92, turn, sl st in each ch back to band. Repeat on the other side.

Checkpoint

Finished front band with cups attached should measure about 14 inches (35.5 cm) across before ties. Lengthen straps or back ties before weaving ends if you need more adjustability.

High-Waist Bottom Panels

Use sc throughout. Ch-1 does not count as a stitch. Work front and back separately from crotch to waist.

Front Panel

Row 1: Ch 15. Sc in 2nd ch from hook and across. Turn. (14 sc)

Rows 2-24: Ch 1, 2 sc in first st, sc to last st, 2 sc in last st. Turn. (+2 each row; Row 24 = 60 sc)

Rows 25-50: Ch 1, sc across. Turn. Fasten off after Row 50. (60 sc)

Back Panel

Row 1: Ch 17. Sc in 2nd ch from hook and across. Turn. (16 sc)

Rows 2-26: Ch 1, 2 sc in first st, sc to last st, 2 sc in last st. Turn. (+2 each row; Row 26 = 66 sc)

Rows 27-52: Ch 1, sc across. Turn. Fasten off after Row 52. (66 sc)

Panel measurements after blocking: Front approximately 10 inches (25.5 cm) wide at top and 9.25 inches (23.5 cm) tall. Back approximately 11 inches (28 cm) wide at top and 9.5 inches (24 cm) tall.

Size Customization

For a taller rise, add even rows before edging both panels.

For more hip width, continue increasing for 2 to 4 more rows on each panel, keeping the final top count even.

For more coverage, line the bottom after blocking and before final elastic insertion.

Bottom Assembly and Edgings

Crotch Seam

With WS together, seam the foundation edges of front and back using mattress stitch. The crotch seam joins 14 front sts to the center 14 of the back foundation edge. Ease the extra back stitch at each side into the leg edge.

Side Seams

Match the top corners. Seam each side for 42 rows from waist downward, leaving the lower leg opening unseamed. This creates a high waist and open leg curve.

Waistband

Join yarn at one side seam.

Round 1: Sc evenly around the top waist edge, working 60 sc across front, 66 sc across back, and 1 sc into each side seam join. (128 sc)

Round 2: Sc around. (128 sc)

Round 3: Ch 1, sc around, leaving a 1 inch (2.5 cm) opening for elastic. (128 sc)

Insert elastic to comfortable fit, overlap and sew elastic ends, then close opening.

Leg Edging

For each leg opening, join yarn at crotch.

Round 1: Pick up sc at a ratio of about 3 sts for every 4 row ends around the curve, adjusting to 96 sc.

Round 2: *Skip 2, 5 dc in next st, skip 2, sl st in next st; rep around for 16 scallops. Fasten off.

Top Scallop

Work a decorative scallop around the upper waist over 126 of the 128 sts: *skip 2, 5 dc in next st, skip 2, sl st in next st; rep 21 times. Work 1 sl st in each of the 2 remaining seam sts to finish invisibly.

Decorative Hip Shells (Make 6)

Make 6 small shell motifs. Sew 3 layered shells on each hip, placing the top shell closest to the waist and staggering the lower two shells by about 0.75 inches (2 cm).

Row 1: Make adjustable ring. Ch 3, work 5 dc in ring. Turn. (6 dc)

Row 2: Ch 3, dc in same st, 2 dc in each st across. Turn. (12 dc)

Row 3: Ch 3, fpdc in next st, 2 dc in next st; rep from across. Turn. (18 dc)

Row 4: Ch 3, fpdc in next st, dc in next st, 2 dc in next st; rep from across. (24 dc)

Edge: Across curved edge, work 4 scallops using the 6-st repeat. (4 scallops)

Placement

Right hip: Sew one motif centered on side seam at waist, one slightly forward, and one slightly back.

Left hip: Mirror the same placement.

Add a pearl at the base of each shell or leave plain for easier laundering.

Finishing, Blocking, and Care

Finishing

Weave in ends securely on the WS, splitting yarn plies where possible for invisible anchoring.

Steam block cups over a curved form or folded towel so the shell ridges open evenly.

Wet block the bottom flat to measurements. Pin scallops open and let dry completely.

For wear, line the cups and bottom with swim or lingerie lining as desired.

Care Instructions

Hand wash cold with mild soap.

Do not wring. Roll in a towel to remove water.

Dry flat away from direct heat.

Remove or protect pearl embellishments before washing when possible.

Troubleshooting Common Issues

Cup too flat: Steam over a rounded form and add a slightly deeper lower pinch before sewing.

Cup too small: Add Row 9 using the same 8-ridge increase logic: fpdc, dc in next 6, 2 dc in next. (72 dc)

Waist too tight: Use longer elastic or add 2 to 4 even rows to each side before seaming.

Scallops ruffle: Use a smaller hook for edging or skip fewer picked-up stitches only at curves.

Fabric see-through: Use lining fabric behind cups and bottom panels.

Final Maker Check

Before wearing or gifting, tug gently on straps, ties, elastic, and pearl attachments. Reinforce any point that receives tension.
