This pattern creates a classic triangle bikini top with scalloped edging, worked in DK cotton for a comfortable beach-ready finish. You will crochet two cups that can slide on the tie for adjustable fit and a customizable back tie length. The pattern includes instructions for Small, Medium and Large cups and tips for adapting cup size to achieve the fit you want. Optional advice for lining and knitting-in elastic is included for water use.

Why You'll Love This Oceana Bikini Top Pattern

I absolutely love this pattern because it blends simple shaping with a decorative scalloped edge that feels special without being complicated. I enjoy how easy it is to customize the cup sizes and adjust the straps so the finished top fits a range of bodies. The pattern encourages creative choices — you can line the cups or add knitting-in elastic for extra support when wearing in water. I also love that it uses DK cotton, which gives a soft, wearable fabric that holds shape well. Making this top is both relaxing and rewarding, and seeing the scalloped edging appear is always satisfying.

Switch Things Up

I love how easy it is to change the look of this top simply by swapping yarn colors — try ombre shades for a gradient effect or contrasting edges for a pop of color.

You can make a mini version by using a finer yarn and smaller hook to create a keychain or bikini doll accessory.

Want a chunkier, more coverage style? Use a bulkier DK or light worsted yarn and a larger hook to scale the whole pattern up.

If you prefer a more secure fit, I often add knitting-in elastic worked with the yarn on the last row of the main cup to help the cup hold shape in water.

Try adding small cups of removable foam or thin swim padding inside the lining for extra modesty and shaping.

I sometimes embroider tiny motifs on the plain cup area to personalize my top — initials, small hearts or waves look great.

For a boho look, use cotton-linen blend yarn and longer back ties to wrap around the waist or tie in decorative knots.

You can sew on small beads or shells to the scalloped edges for a beachy, tactile finish but be careful if you plan to swim with them attached.

Consider changing the scallop size by increasing or decreasing the treble counts in the shell to create larger or smaller scallops.

Play with strap styles — replace the neck strap with braided cords, macrame straps, or adjustable rings for a modern finish.

If you make a set, match the bikini bottoms by using the same scalloped edging for a cohesive handmade swimwear look.

Common Mistakes & How to Fix Them

✗ Not measuring the base of the cup carefully before starting; check the stated cup base measurements and adjust chain length to match your chosen size. ✗ Skipping stitch counts at the end of rows can lead to uneven shaping; always verify the bracketed stitch counts after each row to catch mistakes early. ✗ Crocheting with inconsistent tension causes rippling or tight cups; maintain even tension and practice a swatch to match the gauge before starting. ✗ Forgetting to reattach elastic when planning to wear in water will reduce support; if using knitting-in elastic, fasten off and reattach yarn as instructed at the elastic row.

Info :

After you have done this count back 2 sts from the last st marker. This st is where you will need to sc to from the beginning of the row.

Info :

For example this cup will follow the same pattern as the small cup but with an extra 3 sc at each end of row.

— Back Tie :

Info :

Make a chain to your desired length of a back tie (for reference for a 32" back I chained 250). Then simply sc along ch, fasten off and weave in ends. You can also use an old bikini back tie for this if you wish.

Info :

When finished simply weave the back tie through the FPtr and BPtr at the base of cup. See pictures in pattern for guidance on placement.

Info :

Follow any additional finishing notes: lining recommended if you plan to wear the top in water, and consider knitting-in elastic to help hold shape when wet.

Assembly Instructions

  • Weave the neck strap (ch 90+1 or desired length) into place by securing the strap to the top of the shell at the top centre and weaving the neck strap ends into the shell top before fastening off.
  • Weave the back tie through the FPtr and BPtr stitches at the base of each cup and adjust so both cups sit evenly, then tie to secure and trim any excess yarn.
  • Fasten off all ends and weave into the wrong side of the cup so that they are hidden and secure, then block gently to shape the scalloped edging.
  • If lining the cups, cut swimwear fabric to the cup shape and hand sew the lining to the inside of each cup before attaching the back tie to prevent the lining from shifting.
  • If using knitting-in elastic, fasten off at the indicated row and reattach yarn with the elastic in place, working the remaining rows over the elastic to secure it.

What size will the finished piece be?

Finished cup base measures approximately: Small 6.5" (16.5cm), Medium 7.5" (19cm), Large 8.5" (21.6cm); overall size will depend on strap length and spacing between cups.

Do I need prior crochet experience for this pattern?

This pattern is rated intermediate and assumes familiarity with US crochet stitches such as hdc, tr, front and back post treble; basic shaping experience is helpful.

How do I adapt the cup size if my measurements differ?

You can add or reduce the number of repeats in the main cup rows; count stitches and follow the guide to mark every 6th stitch from the ch1 sp to calculate shell placement.

Is this pattern suitable for wearing in water?

It can be made swim-ready by knitting in elastic where indicated and lining the cups with swimwear fabric; otherwise it is best used as a beach cover or for light wear.
