I love the pattern and shape of this bralette and it is lightweight and comfy to wear. It only came in a combined size option though and I chose the S/M based on my measurements but I would say it's a bit too loose under the arms, even with the straps tightened. The XS/S would have been too small based on my measurements though. I wish this was offered in the standard XS, S, M, L, XL etc as it may have a better chance of fitting me. Love it though and still wearing it any chance I get!
*This review page is asking me to select the size I ordered and my usual size down below, but it doesn't give the option to choose the combined sizes eg S/M.
