We're slobs in this town, and we're sinking the country's fashion into the deep end, left coast first. We know times are hard, but excuses are few, especially when the folks with the most means are leading the way toward sartorial sin. Let's dress up L.A. Here's one way: It's a Wrap has amazing prices on truly prime pieces, some of them handmade in Italy and France. The retailer gets its inventory from Hollywood productions after the clothing has been used on-set once or twice, if that. We spotted a men's Boss dress shirt for $28, an Yves Saint Laurent men's suit for $13 (marked down from $100) and a no-brand black, satin cocktail dress on the Dancing With the Stars rack for $15. Halloween costumes are starting to bloom: Orange prison jumpsuits are going for $15 (Bernie Madoff, anyone?) and women's sailor tops are $8. We even spied a boy's Superman suit for $10. It's a Wrap also has shoes, jeans, headwear, furniture and set decorations. Founded in 1981 by Janet Dion, the store now has two outlets: West L.A. and Burbank. Each has dressing rooms. And there are racks out front with even deeper discounts. It's a Wrap gives purchasing power to the people who know that dressing well is a virtue. 1164 S. Robertson Blvd., W.L.A. (310) 246-9727.
