Crochet Bikini & More: DIY Crochet Trends for Summer 2025

26/07/2025

Bikinis, Tops & Cover-Ups – handcrafted and hot this summer

Summer 2025 is all about color, individuality – and most of all: handmade style. Crochet fashion is making a comeback at the beach, festivals, and in the city. Whether it's a sexy bikini, breezy bralette, or stylish cover-up – with just a few stitches, you can create your very own summer wardrobe.


👙 1. Crochet Bikinis – a classic reinvented

Forget outdated 70s nostalgia – today's crochet bikinis are form-fitting, flattering, and comfortable, with the right stitch even swim-safe.

Things to consider:

  • Yarn choice: cotton with a bit of stretch (e.g. cotton-lycra blends)

  • Lining: optional inner lining for support and opacity

  • Construction: tight stitches like single crochet and slip stitches work best

👉 Tip: Try cut-outs or lace-up backs for a modern twist.

☀️ 2. Summer Tops – from bralettes to festival looks

Light crochet tops pair beautifully with shorts, skirts, or layered over a bikini. Whether it's a crop top with shell edging or an airy mesh shirt – crochet tops are one of the hottest DIY trends for 2025.

Ideal stitches for summer tops:

  • Pineapple stitch

  • Filet crochet

  • Shell or fan stitch

  • Mesh stitch

🧵 Fit tip: Use tie-back straps for adjustability and comfort.

🌊 3. Cover-Ups & Beach Dresses – breezy and flattering

Kaftans, ponchos, and wrap skirts in crochet are must-haves at the beach. Look for ombre yarns, geometric designs, and boho flair.

Best yarns for these styles:

  • Viscose or cotton blends

  • Gradient yarns

  • Slightly shiny finishes (e.g. bamboo or silk blends)

🪸 Style tip: Layer over a simple slip dress for city wear.

📐 Fit Tips for Crochet Fashion

Crochet doesn't stretch like knit fabric, so good shaping is essential: 

  • Bust: Take measurements and adjust increases/decreases accordingly
  • Straps: Always make adjustable (e.g. with ties or buttons)
  • Waistband: Use ties for flexibility
  • Yarn: Smooth yarns drape better for clothing 

🧵 5 DIY Project Ideas for Summer

  1. Shell stitch bikini top – with picot edging and tight stitches

  2. Filet crochet crop top – light and beginner-friendly

  3. Backless bralette with ties – adaptable to any body

  4. Gradient mesh cover-up – perfect with ombré yarn

  5. Wrap crochet skirt – great for beach or festival wear

👙 DIY Crochet Bikini – Top & Bottom (Beginner Friendly)

Perfect for summer 2025 – this easy crochet bikini pattern is simple, stylish, and customizable for different sizes. 

🧶 Materials 

  • 100–150 g cotton yarn with stretch (e.g. Schachenmayr Catania Fine, Lang Yarns Baby Cotton, Pro Lana Ocean Stretch)

  • Crochet hook: 3.0–3.5 mm (US D–E)

  • Yarn needle

  • Optional: elastic thread, lightweight lining fabric (e.g. Lycra or swimwear lining)


👙 Part 1: Bikini Top (Triangle Cups)

Step 1: First Triangle

  1. Chain 15 (adjust based on bust size).

  2. Row 1: SC in 2nd ch from hook, then SC across.

  3. From Row 2 on:

    • Ch 1, turn.

    • SC in each stitch, but in the center stitch: 3 SC (this increases the triangle shape).

    • Repeat until the triangle measures desired size (typically 12–15 rows).

Step 2: Second Triangle

→ Make a second identical triangle.

Step 3: Join Both Triangles

  • Place both triangles side by side, ch 1.

  • SC along the bottom edge of both triangles (add a few chains between cups if you want spacing).

  • This forms the underbust base.

Step 4: Straps

  • Top ties: Attach yarn to top corner of each triangle → ch 60–90, then SC back across the chain. Fasten off.

  • Underbust tie:

    • Either ch 100–140 and SC back to create a tie,

    • or SC along the bottom edge of the cups and add 50 ch each side for back ties.


🩲 Part 2: Bikini Bottom (Classic Shape)

Step 1: Front Panel

  1. Chain 20 (for S/M – 25–30 for L/XL).

  2. Row 1: SC across.

  3. From Row 2 onward:

    • Ch 1, turn.

    • Increase 1 SC at each end of every row until you reach approx. 35–40 stitches (width of crotch).

    • Continue straight (no increases) for 6–8 rows.

Step 2: Back Panel

  • Continue from the front panel.

  • Now, increase 1–2 SC at both ends of each row to widen the back.

  • Repeat until the back panel is about 4–5 inches / 10–12 cm longer than the front.

Step 3: Side & Leg Ties

  • At each leg corner, attach yarn → ch 40–60, then SC back for the ties.

  • For waist ties, you can repeat the same: SC along the sides and add long ch for adjustable fit.


🌿 Fit Tips & Finishing

  • Use elastic thread along with yarn for extra stretch

  • For lining, cut fabric to match cup and bottom shapes and sew in by hand or with zigzag stitch

  • Always make a swatch and adjust hook size if needed

  • Cotton yarns stretch when wet – size down slightly for swim use


☀️ Optional Styling Ideas

  • Shell stitch or picot edges for detail

  • Ombre yarns for trendy color transitions

  • Add a decorative central ring or beads on the ties
