Underwear as outerwear

Underwear as outerwear means wearing pieces of clothing normally worn under other clothes, like underwear, bras, tanks, and slips, on the outside of your outfit. Wearing underwear as outerwear is a way to express yourself in fun and creative ways. You can mix different pieces together to make your outfit unique and interesting. For example, you could pair a long slip with a tank top and some jeans, a corset over a dress, or a bra under an open shirt. Wearing underwear as outerwear can help you make a statement and show off your personal style.
