Aside from maybe the bangs, Sienna Miller's look from last night's annual Theatre World Awards is essentially a reprise of a 2009 look the actress wore while promoting G.I. Joe: The Rise of Cobra. The common denominator? One great Isabel Marant dress from the Fall 2009 collection and a similar styling M.O. In both cases, the actress added ankle boots to complete the snake-print dress, a testament to her cool-girl signature style - and a lesson that there's nothing wrong with wearing the dresses already in our closets.
Every event brings with it the temptation to buy something new, but we're following the lead of style-setters like Sienna Miller and Olivia Palermo who've proven that there's ample styling potential in recycling an old favorite with a quick update. If Sienna can rework a dress on the red carpet, we're pretty sure we can update our own favorite pieces for weddings, cocktail parties, and everything in between. Take in both looks below and let us know your thoughts on her recycled look in the comments below.
