These work great for me. I am a 34DD, so pasties just don't work for me, and I have yet to find a strapless bra that stays up. I bought a black dress with netting top, and these straps worked perfect on an existing bra I had to keep me supporting but have no bra straps. They stretch ever so slightly, but not enough to cause any sort of issues. I really like them, and they work great!
