When I first got my boobs in middle school, they felt so unwieldy, so I slept with my bra to contain them. I guess I got in the habit and so I sleep with a bra on a lot. Sometimes I will take it off before bed if I'm feeling uncomfortable, but more often than not I leave it on, and DH thinks its so weird! And I don't know any other women that sleep in a regular underwire bra - some women I know take their bra off as soon as they get home! What about you all?
