This dress is perfection.  We already have a few aphratti dresses, and we knew how it fit, so we went up a size (M to L for a 120 pound, 12 yo, 53 girl).  It is stretchy, so if you like a very body-con look and want it to be very form-fitting, just order your regular size.  Going up a size makes it more comfy and the color more solid.  We have it in other colors and short sleeved.  Washes well.  Remember to hang dry. LOVE LOVE LOVE.
