Big briefs are for nights out, not just for laundry day: that's what their style-heavy acceptance squad is protesting on the party circuit at the moment. Undergarment flaunters include Miley Cyrus (left), who was at a Moschino and Barbie event in Miami last night (with really ridiculously hot BF Patrick Schwarzenegger) in the label's Spring '15 Barbie pink (natch) cardigan and fishnet pencil skirt, revealing her branded briefs underneath. Meanwhile, for the less shouty-dresser, Hannah Bronfman's approach to showing underwear might be more doable (right). The beauty app entrepreneur was also in Miami at a Paper party thrown for cover star Kim K, wearing a sheer midi skirt and bralet top. This is happening, people.
