I really like this top and used the measurements/size chart but still ended up just a little too big/loose to give any real support in the cups. I’m 38D bra and usually size L or XL in similar items. The chart put me closest to XL based on chest measurement, and says to go with the bigger size if you’re in between. I needed a Large instead but since I had to go out of town, didn’t get to try it on right away. I tried reaching out by email and phone several times bc I knew I was cutting it close and might miss the 14 day deadline if I just put it in the mail, but each time I just received back an email (even to return my phone message) with the same very generic info about returns and no one ever actually responded about whether they would accept it. Now I have a top that doesn’t fit quite right and and can’t be worn without a bra, defeating the whole purpose of buying this particular top.
