This is a lovely dress. it is on the heavy side and lined, so i would not recommend for hot summer wear. but the material and style are adorable. the skirt is definitely a-line, not sheath, but i prefer that. it runs a tad too tight in the chest, so if you're between sizes in the bust, i'd order up. that said, a 6 would be too big for me. i'm 5'4, 120 lbs and 34c and usually wear a 4.
