This suit is super cute and sexy. I am 5'6, 125 and have a long torso - I got the US size 4 and that's the right size - the fit is quite good. That said, if have even moderately "hippy" hips the design accentuates your lower half quite a bit and, depending on how curvy you want to look, it could be too much. Other than that, super cute and the back straps are not only comfortable but, I think, sexy.
