The Crochet Side-Tie Bikini Bottom is a small triangle of scalloped cotton that holds an entire season inside its stitches. It carries the warmth of sun-baked afternoons, salt on the skin, and the quiet pride of wearing something your own hands made.

The Side-Tie Bikini Bottom
This Crochet Side-Tie Bikini Bottom is a love letter to slow summer days. A softly scalloped edge frames the front panel, while a delicate row of open stitches along the waistline adds a whisper of lace to an otherwise structured shape. Long, slender ties loop through each side, so you can adjust the fit with a simple bow and wear it exactly the way you like. It suits the beginner who is ready for a rewarding wearable and the seasoned maker who enjoys a relaxed, meditative project.
The tutorial shows the bottom in a rich burnt orange and a crisp, clean white, and both colors feel like pure sunshine. Think terracotta, sage, soft sand, or ocean blue if you want a calmer palette. Make a matching halter top with the same scalloped trim and you have a set that looks effortless on the beach and charming at a poolside brunch.

Materials and Tools
Choose a smooth DK weight cotton or cotton blend yarn for this project, since it gives clean stitch definition and a soft feel against the skin. A 3.5mm hook creates a snug, structured fabric that keeps its shape, and the light green ergonomic hook in the video is a comfortable choice for long sessions. Mercerized cotton adds a gentle sheen and holds up beautifully to sun and water. Keep a pair of sharp scissors and a blunt tapestry needle nearby for tidy finishing, because the tie ends deserve a neat weave.

Stitch by Stitch
This design relies on a handful of classic stitches that build a fabric both sturdy and graceful.
- CH (chain) Forms the foundation, the open waistline spaces, and the long ties that finish each side.
- SC (single crochet) Creates the dense, supportive body of the bottom with a smooth, even texture.
- DC (double crochet) Adds height and flexibility, especially along the upper edge where the fabric needs a little more drape.
- Puff or shell stitches Form the scalloped border that gives the piece its soft, feminine charm.
The steady rise and fall of these stitches settles into a calming rhythm, the kind that makes the hours pass quietly. Before long the fabric grows under your fingers and the shape begins to reveal itself.
Construction
The bottom is worked from the center outward in rows, beginning at the narrow gusset and widening toward the waistline. Each row adds gentle shaping, so the triangle forms naturally without any complicated assembly. Once the main panel is complete, a scalloped border is worked around the edges and the long chain ties are attached at each side. Beginners can follow the full pattern in the video tutorial, and if you want a custom fit, simply add or remove a few rows to adjust the length before you begin the waistband.
Wearing Your Side-Tie Bikini Bottom
Pair it with a matching halter top for a seaside holiday, or layer it under a flowing white linen cover-up for a sunset walk along the shore. It also looks lovely with high-waisted shorts for a relaxed festival look. Imagine tying that last bow and feeling the sea breeze, knowing every stitch is yours.
Keeping Your Bikini Bottom Looking Its Best
Rinse your Crochet Side-Tie Bikini Bottom in cool, fresh water after every swim to wash away salt, chlorine, and sunscreen. Hand wash it gently with a mild soap, then press out the water in a clean towel without wringing or twisting the fibers. Lay it flat to dry in the shade, gently shaping the scalloped edges and ties with your fingers as it dries. Store it flat or loosely folded in a breathable cotton bag, away from direct sunlight, so the colors stay vibrant all season.
Every scallop and every tie you make is proof that handmade pieces carry a warmth no store-bought swimwear can match. Save this Crochet Side-Tie Bikini Bottom to your summer crochet board on Pinterest and share your finished set with us!
