The Alana runs small, so this is more like a standard 30K. I need a 30KK in most bras at the moment, so this fit pretty much as expected. It's too small in the cup, but what was really the problem was how wide set the straps become. I have a 30K Alana and it fit beautifully, so I was really shocked at how bad this bra fit.
The straps are significantly more wide-set than in a size down, and the sides are far too tall under the arm. I can't tighten the straps enough without the straps/cups digging into my arms/shoulders. Ideally I'd need a 30L for cup volume, but I think the straps and armholes would be unbearable. A 30K in a regular Bravissimo balconette would be far more preferable and should fit the same as this, so I wouldn't recommend buying in this size.
