LOVE IT
I'm pear shaped with a huge rear (J crew S/M tops, 31 jeans, 6/8 in A-line dresses). I ordered a L based on the other reviews and am glad I did, as there is NO give to the waist. The top sits perfectly on my natural waist and hugs my hips in a very flattering way. It's a touch long, I'm 5'4" and it skims the ground when I'm barefoot.
