I've been looking for a bra for sleeping and I didn't want a nursing bra.  This one fits the bill....provides more separation (for large bust) than a sports bra.  The racerback sports bras were uncomfortable to me, this one has regular ballerina back straps.  I would have given 5 stars if material had been a liitle thicker. This bra would not be good for large busted woman to wear as a regular bra, but works quite well for a sleeping bra.  I plan to buy a couple more.
