I have found that these are the only thing I can wear. I was desperate to find something I could wear without breaking out. I finally realized my cotton sports bras were causing too much heat. I thought at first this bra was extremely small for a 3x.  I hung it on a hanger for 2 months in view so I would not forget about it, before deciding to try stretching it, because returning things are a hassle usually.  I finally decided to try stretching it with my arms as far as I could stretch.  That seemed to help quite a bit.  Once it was washed, it was more comfortable.  I have gone through many expensive bras due to breaking out and went through steroids from a dermatologist.  I threw many bras away and tried remodeling some, which I would wind up throwing away.  I like these bras because there is no scratchy itchy lace, no wires that dig into my skin, no metal or enclosures that squeeze your skin.  At least you have some coverage with comfort, but you have to work at it.  I am ordering the next larger size next time, 4x.
