I bought this bra at Walmart for a lounge & sleep bra.  It runs way too small so I bought several sizes before finding the most comfortable one for me.  According to the sizing chart, I should wear a small as Im a 34/36C.  However, I ended up debating between the XL and or 2XL.  I decided to keep the 2XL since some reviews say this bra will shrink after washing.  Its very comfortable and has enought support for me.  I will buy more of these bras but will wait and see if the 2XL shrinks or not after a few washings.
