The other reviews are very inconsistent...some say it runs small, some say runs large.  I can see both, because it fits fine around and the straps are little large yet fine, but the cup was so small. I have to say I am a small girl and even throughout my pregnancy (almost 27 weeks) I haven't gained any weight other than my belly and chest.  My chest went from a 34B to a 36D/34DD, so I ordered a large.  It barely fits, I could really use an XL, but cannot imagine a small girl like me having to buy an XL bra.  I think it will be fine for bed and waking up to breast feed.
