I am a Muslim woman, and I don't think that my choice of lingerie is due to the fact that I cover myself in public (nor do I feel repressed in any way)... The main question of the post has been answered - we can wear what we want in the privacy of our homes, in front of family/other women, etc. Also, remember, just because we are supposed to dress modestly (no tights, waist-synching belts, short skirts, etc) in public, doesn't mean that every Muslim woman abides by this, which is why you still often see these items on many Muslim women.
