This style is meant to be youthful and girly with its short sleeves and wrapped piping. The right front gets attached into the side seam for the look of a cross over version, though the front remains closure-free.
I love the shape of this dress. No matter what your size try to find a dress with an element of 'fitted' somewhere. This fitted waist draws your attention in and the fuller skirt away from the hips. Don't dress baggy all over.
