This bra did an amazing job holding up my substantial bust, and is the only strapless that wasn’t full-corset length that I’ve had luck with. It didn’t budge all night! No sagging, nothing! However, I originally ordered my usual size, 34E, and the band was so tight that my husband seriously struggled to clasp it in the back. And once he did, I didn’t last 30 seconds before I was begging him to help me get it off! It was so tight it was extremely painful on my rib cage. So I ordered a 36D and that fit very well. Another caveat, and I don’t know maybe this is a unique problem to my specific bra, but after about 4 hours of wear, a piece of boning in the side started rubbing my skin raw and really hurting on the top and bottom ends. It seems that it shifted a bit in its casing and wasn’t laying flat against my body. Up until that point, I was more comfortable than expected considering it’s a strapless and my boobs are pretty heavy
