If you have a smaller chest, this top will unfortunately not work for you. I wear a 44B and was swimming in the 2x cups. The 1x was also slightly too big in the cups, which would have been fine, but the band was too small to close comfortably and I would not feel secure being active in it. Plus it didn't lay flat at the back so it didn't look very nice. I really hope Additione Elle starts to consider their customers with smaller chests. So disappointed this did not work out, as it's such an attractive swim top and a great length. By all means offer extended cup sizes, but think about other plus sized bodies as well. All I want to do is spend money at your store but all of your swimwear this year is a major fail for my body type.
