The Details

Saint Tropez Bikini

Nautical, but make it effortless.

A cobalt and cream stripe crochet set that looks like it was made for the South of France and packed for everywhere else. The triangle top ties at the neck and back with scalloped crochet edges that add just enough detail without overdoing it. The boy shorts match in the same stripe knit with a solid cobalt waistband — the kind of set that looks intentional whether you're dripping poolside or walking straight into lunch. Texture, colour, and a little bit of coast wherever you wear it.

She's the harbour at golden hour. The striped tote and the rosé. The set that makes a pool look like the Mediterranean.

Details:

  • Triangle top with halter neck tie
  • Scalloped crochet edging throughout
  • Cobalt and cream horizontal stripe crochet knit
  • Boy shorts bottom with low-rise fit
  • Solid cobalt waistband
  • Open-knit fabrication — style over swim underneath
  • Sold as a set
Size & Fit

  • Fully adjustable halter ties for a customised fit
  • Triangle top offers light coverage with a flattering plunge
  • Crochet shorts sit low on the hip with a relaxed, breezy silhouette

Fabric & Care

Fabric & Care:

  • Handcrafted open-weave construction with a textured, artisanal finish
  • Soft, breathable natural fibre — lightweight and perfect for warm weather
  • Hand wash cold separately, lay flat in the shade to dry
  • Do not wring, bleach, or tumble dry
  • Do not iron directly — steam only if needed
  • Handle with care to preserve the delicate crochet structure
  • Store folded flat to maintain shape (avoid hanging, which can stretch the knit)

soo good, not just good for the price either

March 01, 2026

I bought this expecting it to be good for the price, it is actually one of my favorite outfits The detailing is insane up close. Photos do not even do it justice.

Feels like a $500 outfit

March 10, 2026

I have owned a few higher end dresses and this honestly shocked me. The weight, the finish, the way it sits on my body, it feels expensive.I actually never to take off.

The adjustability is next level. You can get that exact fit where it is snug but still comfortable all day. I also reached out before buying and they answered everything properly, not some copy paste reply.

Thought it was Dior

March 03, 2026

No joke, first time I wore it out, someone asked if it was Dior. The weight, the shine, the way it sits... it does not feel like a cheap alternative at all. It just feels expensive.

Got asked if it was a designer

Jan 22, 2026

I wore this to dinner and my friend literally grabbed my body to look closer. She thought it was a designer until I told her otherwise. Insane value for what you pay.
