But, it's a great wild thought. Thank you for bringing it up. I do have a couple t-shirt style bras that are thinly padded, that should serve the purpose well. like a lot of them, they're not really full cups, but should still keep most of the heat in. If I need any more heat retention than that, I guess I could make a bra out of a survival blanket?
Thanks for the tip, Wishful!! Patti
And, I think I'll just go ahead and wear one to bed. Why wait?
