Size up
This dress is everything i imagined it would be. lightweight, flattering on my hourglass shape, and comfortable. i am a true 4p in retailer dresses (5'4" 32d, 27 inch waist, 28 denim size) and purchased this dress in a 6 regular. i imagine the petite size would be way too short, as the regular size hit about 3 inches above my knee. might be a problem for taller girls. definitely size up on this one to avoid button gaping.
