I know that breastfeeding is not the intended use of this bra, but I bought one out of desperation to find a nighttime bra that I could pull down to breastfeed in AND stand to sleep in.  If this is your predicament too, look no further.  This bra fits snugly enough to hold breast pads on, but there are NO UNCOMFORTABLE SEAMS to irritate you while you try to sleep.  I bought a MEDIUM (I am a 34C).
