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.
