(This was a gift for my daughter. This is her review.)
The fit is true to size, I love the adjustable waist band, and the jumpsuits are very high quality. The fabric is very stiff (although I haven't washed them yet so that could change), and I wish that had been described. The fabric's stiffness makes the fit very structured, which the online images don't show.
Rated 0 on a scale of minus 2 to 2, where minus 2 is Runs small, 0 is True to size and 2 is Runs big
