3. Dc in each chain to end. (You will have 13 dc.)

Row 2 (Corner Increase)

Row 3 and All Following Rows (Triangle Shaping)

8. Dc in each stitch until you reach the corner (the two chains in the previous row).
9. In the corner space: Work (2 dc, ch 2, 2 dc) in same space (this forms the pointed tip).
10. Continue dc in every stitch to the end.
11. Ch 3, turn. Repeat as above.

Increasing the Cup

• After every row, you add 2 new dc (one per "side") as you increase at the top/center.
• For Size G/L: Make 14 rows (count rows on one side only).
• For Size M: Make 12 rows.
• For Size P/S: Make 10 rows.

(Adjust as needed for coverage—try on as you go!)

2. Creating Spaces for the Underbust Cord

12. At the last row's base: Ch 3, turn. (Acts as first dc)
13. (Dc, ch 1, skip 1) across the whole base edge to form a row of dc, ch 1, skip 1 mesh spaces.
14. When you reach the tip, fasten off.

3. Decorative Edging Around Cup

24. (Ch 2, sc in next mesh/space) repeatedly along the interior bottom edge, bridging the mesh gaps.
25. At end, weave in and hide all tails.

6. Assembly

28. When wearing, tie the neck straps and back cord to fit.

Tutor’s Suggestions

• Customization is key: Try the cup against your body and adjust number of rows or chain length for best fit.
• If you prefer more coverage or support, add extra rows to each cup.
• Weave ends neatly to avoid loose threads—or unraveling at the beach!
• Use a color that matches your style. The elastic and quick-dry properties of Verano yarn make it perfect for swimwear.

Uses

• Swim top/bikini
• Bralette for layering
• Festival/carnival fashion or summer beachwear
• Makes a wonderful, quick summer gift!

Tip

Block your finished top: Gently wet and shape cups over a round surface (like a bowl) and air dry to ensure perfect drape and shape!
