Watermelon-Themed Bikini Top Crochet Pattern

Create a fun and vibrant watermelon-themed bikini top that’s perfect for summer outings or beach days. This stylish and unique crochet top is designed with a bright red for the main part of the cups, a sweet touch of white for the rind, and a pop of green for the outer edge. Black spots are added to mimic watermelon seeds. Perfect for intermediate crocheters, this project combines color changes, shaping techniques, and decorative stitches for a playful and functional piece of clothing.

Skill Level

Intermediate: This project is suitable for crocheters who have a basic understanding of working double crochet stitches, chain stitches, and color changes. Some experience shaping crochet projects is also helpful.

Materials Needed

To create the watermelon-themed bikini top, gather the following materials:

Yarn:
- Red (main color for the cups)
- Green (watermelon edge color)
- White (to mimic the rind of the watermelon)
- Black (for the embroidered seed details)
Crochet hook: 3mm crochet hook
Tools: Yarn needle and scissors
Optional: Tape measure for checking sizing

Special Stitches Used

Bobble/Puff Stitch: To create the decorative puff edging in the green section, work 4 double crochets into the same chain space, then pull the loop through the first stitch of this cluster to form a puff or bobble.
Center Shaping Stitch: For the center chain-1 space, always work [2 double crochets, chain 1, 2 double crochets]. This creates a shell stitch effect and helps shape the curve of the bikini cup.

Stitch Abbreviations

ch: Chain
sc: Single Crochet
dc: Double Crochet
st: Stitch
sp: Space

Useful Tips

Use a stitch marker to keep track of your chain-1 spaces in the center of the piece. This will help you position your [2 dc, ch 1, 2 dc] clusters consistently in every row.
Practice even tension, especially when working the bobble stitches in the green section, to ensure that the puff stitches stand out evenly.
Test the strap lengths by tying them on your body to ensure the perfect fit. You can add or remove chains from the straps to suit your preference.
For a polished finish, block your project after you complete it. This will ensure the edges remain flat and your stitches look neat and even.

Step-by-Step Pattern

Foundation

Ch 17: This acts as the foundation chain for one bikini cup.

R1

Skip 3 ch from the hook.
Work 1 dc into each of the remaining chains across.
In the last stitch of the row, work (2 dc, ch 1, 2 dc) to form a corner.

Rows 2–6 (Red Section)

R2: Ch 2 to turn the work, then work 1 dc into each stitch along the row.
In the center ch-1 sp, always work (2 dc, ch 1, 2 dc) to shape the cup.
Repeat R2 for Rows 3 to 6. Make sure to maintain the center stitch shaping.

White Row (R7)

Switch to white yarn.
Follow the same pattern as Rows 2–6: Work 1 dc in each stitch across, and in the center ch-1 space, work (2 dc, ch 1, 2 dc). This adds the watermelon rind detail.

Green Rows (Outer Edging)

Row 8 (Green):
- Ch 3, turn the work.
- Work the following pattern across the row: ch 1, skip 1 st, dc in the next st.
- In the center ch-1 sp, work (dc, ch 1, dc). This keeps the center shaping intact.
Row 9 (Green – Puff Edging):
- Ch 2 to turn the work and begin a bobble/puff row.
- In each ch-1 sp from the previous row, work 4 dc, and use the starting loop of the cluster to make a puff. Ch 1 after each puff stitch.
- Work the following pattern: Puff stitch, ch 1, sc into the next space between stitches. Continue until you reach the center.
- In the center ch-1 space, work one (dc, ch 1, dc) as per the general pattern rule.
- Continue creating puff stitches and single crochets for the remainder of the row.

Straps & Joining the Cups

For each cup’s strap:
- Attach the yarn to the upper corners of each cup.
- Ch 100 to create the cup straps. You can adjust the strap length as needed.
To join the cups:
- Align the edges of both cups.
- Work sc along the inner edges to join them, leaving a ch-3 gap in the center for flexibility.
Once joined:
- Work a final row of dc stitches across the base of both joined cups for reinforcement.

Main Strap (Underbust)

Attach yarn to one end of the joined cups.
Ch 250 to create the main strap, which will be used to secure the bikini top around the underbust.

Finishing Touches

Using black yarn and a yarn needle, sew small embroidered dots randomly along the red sections of each cup. These will serve as the “seeds” of the watermelon design. Ensure the stitches are evenly spaced for a neat and realistic result.

Assembly and Sizing

Once assembled, the sizing of the watermelon-themed bikini top will depend on your foundation chain length and the total number of rows worked. With the instructions provided, the top should comfortably fit a small to medium size. To adjust for different sizes, you can increase the foundation chain and add more rows to each section (ensure the stitch pattern remains consistent). Always check the fit as you go for the most accurate results.
