These are really nice bras but I appear to be between cup sizes, so ended up in a Maidenform strapless instead (they run about 1/2 cup size small, which works for me). A note on CK's size chart: according to it I should've been a 34A, which surprised me as I'm currently a 32C in all my other bras, including CK. Sometimes sizing can be weird with strapless, so I tried the 34A along with 34B, 32B & 32C, and the latter was the closest to fitting. So my advice is to ignore their chart, start with your regular bra size and go from there.
