Bought this so I could be fully supported during some high impact sports, and still have the option to nurse my 12 week old daughter who was accompanying me. The bra was very supportive. The chest band was perhaps a little bit on the tight side so I had it on the furthest out clasp, but it was still very comfortable, and bras stretch! The cup sizes fit perfectly, and it was incredibly easy to use for nursing. My only complaint would be it's required to be hand washed cold which I don't have time for with a new baby, so it went through the machine on a cooler cycle. Seems to have survived.
