Petite all the way
If you are on the shorter side, do with the petite size. i ordered both (at first, petite was sold out) so glad i got to get it. i looked lost in the regular size, the back length was well below my bum. both colors are really nice, but i did end up with the orange one, more "dressy", red one looked more calsual (though it is a casual shiryt, i had on trousers, and hte orange looked nice with them).
