I bought this, I paid for the xpress shipping and wowza it came quickly. I also had purchased it with the thought I'd have to wear a bra underneath, just because rarely do I ever find a swimsuit that gives me enough support. My cup size is beyond a K...(and I don't know if that's Uk OR US, I find that all confusing) regardless, I was stunned that this fit me...stunned. We will see how it works in water but shocked it's ok on it's own. And I bought a 14 and a 16. 16 is ok but 14 holds the girls better I'd say. I don't like a lot of cleavage but this is a swimsuit so, I have to just deal with it. AND the 16 is needless to say a bit longer and a bit larger...anyway so far I'm really happy with this...very shocked that I don't need extra support with this. So far no uniboob either. I wear a 14 or 16 usually.
