Short, tousled bobs (as seen on the likes of Scarlett Johansson and Keira Knightley) may be having a moment, but if recent celebrity styles are any indication, this tousled texture is moving into updo territory, too. While Carey Mulligan twisted her short bob back into a modified French twist and Eva Longoria opted for a voluminous, slightly mussed-up take on the style, Leighton Meester looked casually sophisticated sporting this piecey bun. Do you love these perfectly imperfect coiffures, or do you prefer your updos sleek and clean?
