This bra is constructed out of similar fabric as the oh-so-wonderful Halo bra from Wacoal, but is necessarily built a little differently. It seems just a tad larger than the Halo bra, although I tried on a smaller size and that was too small. I wear a 34DD and there is enough support for the strapless look, but I wouldn't say I love the shape it gives my breasts. Still, strapless bras are tough and this one is the best I've tried.
