I have this bra in a few colors: allure, black/blondie, elsa pink, and they all fit differently.  I originally ordered them all in 30G, but I found that the center gore, and thus the cups, were different.  I really like this unlined bra and the colors that are offered, so I exchanged them until I found the correct size for each color.  If I didn't like the bra so much I would have considered it too annoying to deal with.  I love the style, and I don't think the fabric is uncomfortable (it's not silk, let's be honest).

I recommend this bra for larger busts who don't care about nipple coverage, I would just tell you to be prepared to order multiple sizes to find the fit for you.
