Safe to say Kate Beckinsale’s favorite pair of jeans are J Brand Viper Leggings, what else would a starlet wear while doing her Christmas shopping at Calypso (a great shop on Sunset Plaza Drive). She once again looks amazing in the jeans which are coated to resemble leather yet comfortable as your old favorite jeans. We have seen her wear the Vipers with a military jacket and earlier this year with just a plain t-shirt, demonstrating one of the benefits of J Brand’s clean look is the ability to wear their jeans with multiple outfits!
