Swimsuit Cover Up Crochet Pattern (Atlantis)

Before You Get Started

Here are a few helpful things to know before diving in:

Perfect for advanced beginners who want to expand their skills!

This pattern uses basic crochet stitches (US terms), including treble crochet, half double crochet, and bobbles.

The cover-up is crocheted in two long panels, seamed together with space for your head and arms.

You’ll finish the look with an I-cord belt and tassels for easy styling.

Tools & Materials

Yarn

• 4 x Martin’s Lab Yarn (Color: Atlantis – fingering weight)
• Alternative: Any fingering, DK, cotton, or lightweight yarn

Hooks

• 7 mm (No US Size) hook (for looser bobble border and optional I-cord)

2️⃣ Add Bobble Borders to Short Ends

• Work the bobble stitch border on the short ends of each panel
• Row 1: HDC across, ch 1, turn

You’ll have a bobble edge on all four short sides when complete.

3️⃣ Seam the Cover-Up

With wrong sides facing:

• Seam panels together (center seam): SC 20 inches (51 cm) on both sides
• Leave the center unseamed for the neckline

Side Seams:

• SC the sides together for 16 inches (41 cm), leaving large armholes

Adjust seaming length to customize your neckline depth or armhole size.

4️⃣ Make the I-Cord Belt

Belt length: ~82 inches (208 cm)
Add tassels to both ends.

I-Cord Instructions (crochet version):

• With 3 loops on your 4.5 mm hook:
• *Pull up a loop through 2nd and 3rd ch from hook (3 loops total)
• Slip 2 loops onto needle, ch 1
• Return loops to hook one at a time, ch 1 after each*
• Repeat until desired length
• Add tassels
• You can watch this video here to see how I created the I-cord.

5️⃣ Finish and Block

• Weave in all loose ends
• Gently wet block the cover-up to shape
• Use a wool wash, towel roll to squeeze out water, and lay flat to dry
• To seam your swimsuit cover-up to have a front panel and a back panel – lie flat on a large surface to begin.
• With the wrong sides facing, sc the edges together for 20 inches/51 cm.
• Turn the work and repeat – sc the edges together for 20 inches/51 cm.
• This will leave a long opening in the center of the work – for your head to fit through.
• After that, you will need to sc the sides of the piece together – with the wrong sides facing sc the edges together for 16 inches/41 cm.
• Rep on the other side.
• This leaves long open armholes.
• *Please note – you can seam shorter or longer lengths than I have shown depending on your own preferences – if you want the neck to be less or more open.
• If it is more open (a shorter seam), you will have a better view of your cleavage and back! The V will be larger.
