It's nice to know fashion editors agree: Old Navy jeans are the best budget buy. SELF magazine editor Lindsay Huggins – aka "Denim Doctor" gave me the scoop last week on "Shop Girls." Her favorite is the Old Navy Diva jean, which she calls a universal fit. It comes in various rises and skinny, wide or boot cut. She tried it on 10 magazine staffers and said it worked for all of them. Other jeans under $50 worth trying: Gap and DKNY. Of course, Huggins isn't giving up her premium denim entirely. She love, love, loves her J Brand jeans – as do Eva Longoria, Heidi Klum, Katie Holmes and even Vogue editor Anna Wintour. Find them locally at Bluebird Boutique and Neiman Marcus. Prices start at $150. Good thing you'll have those Old Navys to fall back on for laundry days.
