This bra, contrary to the opinions of some, does not run small in the cups. The band runs 1" too tight, ie, it is a 30 band that only stretches out to 29". That being said, the 30DD cups are truly 30DD cups. They were too big for me. Luckily, I also ordered the 30D bra and that one fit.
Anyways. The wires are extremely broad and the cups are shallow. It is open at the top of the cups, so this is a good bra for those who have very broad roots, are shallow, and might be FOT and/or have tall roots.
This is the best fitting strapless bra I've found! The fit/sizing is similar to the Freya deco strapless in the same size, but with a lower gore (yay!) and VERY firm band. This would be great for those who need a (tight?)26, as I measure around 24" and it stays up on the loosest hooks. I haven't worn it, only tried on, and will update with measurements etc.
