Only worn this once but it was alright for a seamless strapless bra! It is super comfortable and the underwires don't pierce your ribcage! The bra kept slipping down when I wore it (probably because my boobs were to big for it and I got the wrong band size) but it'll fit well for a 34A girl! The only drawback was that I got it in the totally wrong size, however if someone were to wear this with the right size it would be the best strapless bra out there because it is comfortable! I bought this in Thailand's Wacoal (for extra information)
This is a fairly good bra. The straps stay put, and the band fits nicely. The cup covers a little less than three-fourths of the breast. Underwire does not poke or prod, although the bra doesn't give much support, though this may be because I am not in the correct size.
