I ordered twice from them and I had to send binders back. First time I was in the middle between small and medium, ordered a small and was not able to breathe. I asked them via email and they told me to get a medium which would have been perfect dor my messumrements. But when I put that on, I started having a pain in my chest after 2 hours and I had to take it off. It scared me. I sent it back again. They told me to try the large. According to the measurements table on their site, it will be enormous for me... but I ordered it nevertheless because.m I do need a binder and medium scared me. I am now waiting for it to arrive, I will let you know....
