Jessica Alba, Paige DenimSplash News; Time Inc. Digital Studio

Step aside, skinny jeans. There’s a new style in town—and who better to demonstrate its wearability than the ever-trendy Jessica Alba? While out visiting a friend in Brentwood, the Dear Eleanor actress and entrepreneurial mom of two showed off her tomboy style in a tailored yet slouchy fit by Paige Denim that’s straight from your BF’s closet. The Jimmy Jimmy Skinny jean is as versatile as can be: Dress it up with bright pumps and a button-down blouse, or dress it down à la Alba with ankle booties and a trendy moto jacket (hers is Members Only).  What’s more, these baby blues are also a fave of Sarah Jessica Parker’s and Natalie Portman’s—and now they can be yours too!
