I had to return this because, even after I went to their website and ordered based on their size guide, this bra was way too tight.  Since I wanted to use this for sleeping, I didn't want anything tight.

Because I didn't want to risk getting another one and not having the next size work, I went to WalMart and found a package of three bras for half of what this one cost, and they are very comfortable.

The only reason I gave this two stars is the fact that it looked well-made, and the quality was good. I hope others have better luck with the sizing than I did.
