My Bralette One Piece
Simple One Piece w/ Triangle Bralette
Runs small - encourage sizing up.
XS to fit a size 0 or petite 2, size L to fit a 6/8
For example, I'm a size 26/27, 34A & 5'7" (normally wear a small & a 4 or 6 in one pieces) - I am in between a size Medium and Large in this suit.
I opted for a Large for a looser fit w/ more give, but could have been happy in a medium if I wanted a more compressed fit.
