This set kinda looks like lingerie to me and that’s why I love it. I would say this does run small,but in the same way all of their bikinis do. I normally get a medium in fashion nova bikinis and got a medium in this and it fit like usual just small for mediums in general lmao. I’m 5’7 & 130 pounds. The one thing I will say though is it seems like the cup in the top is made for a smaller chest,I’m a DD and nips are covered but BARELY. so as long as you don’t mind that then get this you’ll love it. <3
