This Stella York dress is white lace and tulle over a white fit to flare gown with an optional white sparkling beaded sash. It zips up at the back under diamante buttons. I wear a size 2-4 normally and bought this dress at US size 6. I had it taken in a little at the waist and the bust. I am 5 foot 6 and wore flats on my wedding day. I did not get additional cup inserts at the top as the dress is form-fitting and supportive on its own (no bra needed, I am usually a 34B). It does bustle at the back for dancing and walking around. I wore it in Aug 2016.
