I'm throwing out a drawer of bras that have lost their shape or serve no other purpose than to know I'm wearing a bra. Bra straps are very painful to my shoulders, so I try to find a strapless bra that will stay in place. I bought one bra and liked it so much I bought two more.
One out of the three stays in place if worn strapless. The other two, ennhh. I then put the straps on the first one and was so surprised that it didn't hurt to wear it. The straps are designed to be further out on the shoulder than other bras, a plus for me. The bra looks GREAT and stays in place with the straps on, and I can tolerate it. So, now I have one I wear strapless and two I wear with the straps.
