In the early 2000s, pop stars like Britney Spears and Christina Aguilera popularized the ultra low rise jean. Denim also became a fashion staple once again, becoming an appropriate item of clothing to wear out on a Friday night or even to the office. Flare and boot cut denim were among the most popular cuts and came in a variety of washes. The mid-to-late 2000s saw a resurgence in the skinny jean and distressed (ripped) denim. High-waisted wide leg denim and Boyfriend jeans also came into fashion. An interest in premium brands also soared in the 2000s, with brands like 7 for all Mankind, Citizens of Humanity and Hudson Jeans suddenly becoming mainstream household names.
