Size charts are bizarre. Whatever size it says you are, go the next size up. Bralettes are kinda supportive but not as hoped and bought as didn’t want marks anymore from wired bras. Instead got a way worse thick mark from the bralette. If you are someone that cares about shape then you may like to consider this: I was shocked to see the shape of my boobs wearing a bralette when I put my top on… instead of a nice shape and outline, almost flat and looked saggy boobs! Will wear for dossing around but defo not for me. The only reason I’ve given two stars is for the excellent customer service.
