I typically buy a 36 inch band, but they end up getting too big as the threads stretch so I purchased the 34DDD. Ive been going through several bras, especially for exercise, but I wanted one with underwire. This bra has seriously met my expectations and beyond. At first it felt tight, but after a day of wearing the fabric contoured to my shape well. Its a great bra for true and actual full coverag. The support it provides is better than I ever thought any bra could give. And it keeps everything in place perfectly. Its good for working out or just everyday where. Also, the shoulder straps are hooks so you never have to worry about the straps coming loose throughout the day.
