Pattern Notes

This pattern is worked flat in one piece from the waistband down. The stripe sequence creates a beautiful mosaic effect, while the lace panel adds a delicate, airy touch. Always end with a WS row before switching sections unless otherwise noted. Blocking is essential to open up the lace and achieve the correct measurements.

Waistband

CO 80 (90, 100) sts with color A.

• Row 1 (RS): K1, *K1, P1; repeat from * to last st, K1.
• Row 2 (WS): K1, *P1, K1; repeat from * to last st, K1.

Repeat rows 1-2 for 1.5 inches, ending with a WS row. This ribbed band will form the waistband, providing stretch and a snug fit.

Body – Stripe Pattern

Switch to color B.

• Row 1 (RS): Knit all sts.
• Row 2 (WS): Purl all sts.

Work 4 more rows in B (total 6 rows). Then switch to color C and work 6 rows in stockinette (knit on RS, purl on WS). Switch to color D and work 6 rows. Switch to color A and work 6 rows.

Repeat this stripe sequence (B, C, D, A) until the piece measures 6 (7, 8) inches from the cast-on edge, ending with a WS row. This creates the main body of the bikini bottom with earthy, horizontal stripes.

Lace Panel Insert

Switch to color B.

• Row 1 (RS): K1, *K2tog, YO; repeat from * to last st, K1.
• Row 2 (WS): Purl all sts.
• Row 3 (RS): Knit all sts.
• Row 4 (WS): Purl all sts.

Switch to color C and work 4 rows in stockinette. Switch to color D and work 4 rows. Switch to color A and work 4 rows.

Repeat the lace panel sequence (B, C, D, A) once more, then continue with the main stripe sequence (B, C, D, A) until the piece measures 10 (11, 12) inches from the cast-on edge, ending with a WS row. The lace panel adds a delicate, eyelet texture that beautifully contrasts with the solid stripes.

Crotch Shaping

Now we’ll shape the crotch area by decreasing stitches gradually.

• Next RS row: K1, SSK, knit to last 3 sts, K2tog, K1. (Decrease 2 sts)
• Work 3 rows even in stockinette (purl on WS, knit on RS).

Repeat these 4 rows until 40 (45, 50) sts remain, ending with a WS row. This creates a tapered, comfortable fit for the crotch area.

Leg Openings – Right Side

Next RS row: Knit across the first 20 (22, 25) sts, place the remaining sts on a holder. Work even on these 20 (22, 25) sts for 2 inches, ending with a WS row.

• Next RS row: K1, SSK, knit to last 3 sts, K2tog, K1. (Decrease 2 sts)
• Work 3 rows even.

Repeat these 4 rows until 10 (11, 12) sts remain. Bind off all sts loosely. This forms the right leg opening with a gentle curve.

Leg Openings – Left Side

Return the held sts to the needle, attach yarn at the inner edge (RS). Work even for 2 inches, ending with a WS row.

• Next RS row: K1, SSK, knit to last 3 sts, K2tog, K1. (Decrease 2 sts)
• Work 3 rows even.

Repeat these 4 rows until 10 (11, 12) sts remain. Bind off all sts loosely. This mirrors the right side, ensuring symmetry.

Finishing

Weave in all ends using a tapestry needle. Block the piece to the specified measurements, stretching gently to open up the lace pattern. This step is crucial for achieving the perfect fit and showcasing the intricate stitch work.

Fold the waistband in half to the inside and sew down, leaving a small opening to thread elastic (optional). Thread 1/2-inch elastic through the waistband casing, adjust to fit, and sew the opening closed. This adds extra security and comfort for wear.

Your Desert Mirage Boho Bikini Bottom is now complete! The earthy stripes and delicate lace create a stunning, one-of-a-kind piece that’s perfect for summer. Enjoy your handcrafted swimwear and the compliments that come with it!
