NWOT. Ended up going with a different dress. Plus women’s 20. Ivory. Long sleeve with cut work. Snap in spaghetti strap layer under main dress. Deep slit in front of dress. Backless style. I’d usually wear a 16/18 in stretchier dresses so I sized up and the dress fit perfectly with room to breathe and move. My reason for going with a different dress was that I couldn’t find enough breast support that wouldn’t show in the back since it’s sheer.
