This dress truly is a work of art and i am becoming a little obsessed with byron lars' clothing line. this is my 3rd dress by him and i have been a size 2 in the other dresses. the 2 does fit in this dress but it is a little snug. not sure if a 4 would look as good because it is meant to be form fitting. the panels trick the eye into making you look thinner too. my dimensions 32c,26,33. it fits perfectly in the hips and waist but is tight on top.
