More coverage, same bold check. The Rusty Check Moi Midi Tie Sides Bikini Bottom is cut from 135gsm 92% nylon, 8% spandex mesh in a midi cut silhouette with adjustable side ties that give you a flattering, customisable fit with more coverage than the Brazilian. A vibrant Multicolour Check colourway that ties the full Check Moi collection together — pairs perfectly with the Check Moi Multiway Bikini Top or Tankini Cami Top for a coordinated set.
Why You'll Love It
The 135gsm nylon-spandex mesh is lightweight, quick-drying, and has just the right amount of stretch to move with you in and out of the water. The midi cut gives that confident, flattering coverage that sits higher on the hip than a Brazilian cut — ideal if you want a little more coverage without sacrificing style. The adjustable side ties let you dial in the perfect fit and make it easy to take on and off, while the Multicolour Check colourway gives you the flexibility to mix and match across the full Check Moi collection for a coordinated or contrast look.
