34D -Finally a top with straps that don't dig into my shoulders! The style is so cute! Sewn in the back, but easy to get on. Super soft fabric and the best fit. There is a bralette style band that is Sewn in to keep the ladies up, but you can't see it from the outside, so there's more style to focus on than individual breast like most bikinis. Really love the overall design, fit and fabric! Per instructions, size down one size for the appropriate fit.
