I brought the S/M (I'm a size 8-10, b cup, 174cam with a long torso) I found the overall size OK, very generous in the cup area and the adjustable bra strap is already at its smallest/shortest which for me so would prefer if it could be made smaller/tighter. The overall bodice length is a bit short for me but the garters are really generous in length. None of these things impact the overall wear/look but if you are comparing what you look like to box its not quite the same fit which is a little disappointing. Not sure if I would buy Baci again, the general S/M or M/L sizing doesn't really work for me.
