This bikini was an immediate add to cart - wearing XS on top (ties in the front and back so very adjustable) - bottoms run very small and very, very cheeky but they are so cute with the velvet and crochet sides! I’m typically an XS but could have sized up to medium on those. Shorts are extra small, I have them in three colors (wearing XS, run baggy and large but very forgiving with elastic) LTKSwim LTKSeasonal
