Take your styling cues from the girls who have been doing this since the slip dress resurgence of 2015, and wear your underwear as outerwear. Designers like Versace, Etro, Giorgio Armani, and Prada have amped up the pre-existing short shorts trend by creating pieces that look like boxer shorts. For Spring 2020, think short shorts in silky satins and shirting fabrics, either teamed with t-shirts and sweatshirts, or worn as a matching set.
