I tried a regular 0 in-store and it was more billowy than i would like. i'm usually a size 2/4 and 5ft tall. i ordered a petite 00 and i'm hoping the fit will be more snug and that the length will be more proportional to me (the reg 0 hit just above my knee, but it might be cuter mid-thigh). it's a cute dress that can be dressed up or down and i hope it will work out.
