Recycling Fashion: How Stars Re-Wear and Re-Style Pieces

To walk her dog, Olivia Palermo downplayed her sleek minimalist Rebecca Minkoff blazer and matching cami with distressed denim and nude flats. A day later, she styled it up-shrugging the blazer over a lemon-hued top and a printed midi skirt.

It's all about the accessories. Host Cat Deeley first wore the black-and-printed Etro dress on the July 2nd episode of 'So You Think You Can Dance,' slicking back her hair, adding drop earrings and stacking bangles on both wrists. At the Young Hollywood Awards, she nixed the earrings, kept the bangles and shouldered an emerald Bulgari purse.

A good hat can go with anything. Jessica Alba topped off her patterned Sam & Lavi maxi with a black wide-brimmed sun hat for a dual-tone ensemble. For another look, she took a more colorful route, grounding her fuchsia dress with black accessories.

Sandra Bullock’s go-to footwear during 'The Heat' premieres? These L.A.M.B. booties. She wore them first to complete her all-black monochromatic look and again to break up her cobalt blue ensemble.

Reese Witherspoon matched her white Givenchy carryall to her white jeans and slipped into go-with-everything sandals. In just mere days, she did it again, selecting shorts and swapping out the bold red tee for a blue printed top.

This accessories savant knows how to make add-ons work for her. Olivia Palermo belted her ivory Christian Dior blazer, cleverly transforming it into a top over her iridescent organza skirt. Several days later, she dressed up a white skirt with the same embellished belt.
