If the resurgence of crop tops, Doc Martens and Newsies wasn't proof enough that the '90s revival is in full swing, here's the teaser trailer for "Settle Down," No Doubt's first music video since the band went on hiatus in 2004 (yes, technically that's the aughts, but I think we can all agree that the Tragic Kingdom, released in 1995, was their heyday). Gwen — no surprise here — looks as foxy and youthful as ever.
