Teenage daughter and lingerie.

Recently, my teenage daughter has started to walk around the house wearing just a camisole and boyshort panty. One day, she came home from shopping with a bag of sexy lingerie. When I asked her why did she buy them, she said she will only wear them to sleep. Should I be concerned? There are no male siblings in the house. And if there’s really a male sibling at home, how would things be different? Also, is it ok for a mother to be wearing sexy lingerie to bed after having children? Pls advise.
