Hi Fabbers!

I'm not sure what topic this should go in, so I'll tag it as dressing, though it may technically be off-topic.

In one of the links in the earlier bra discussion, a well-endowed blogger mentioned that she sleeps in a bra. Which made me wonder: is there a compelling reason to sleep in a bra or other supportive garment? Is there a compelling reason not to? Is breast health or gravity at stake, or is it simply a matter of comfort?

For the record, I'm on the well-endowed side of the spectrum, and I generally sleep in pyjamas, with no supportive garment. I learned this habit from my mom, and her arguments were comfort and air circulation. I'm not necessarily looking for a poll on undergarment choices (though that would be interesting), mostly wondering if there's good reason for one or the other.
