We imagine that celebrity closets are stocked with statement pieces, custom-made designer couture, and the most jaw-dropping heels — but sometimes it's just their impeccably chic basics that prove the most inspiring. Cut to us drooling over three perfect iterations of the army jacket, and that's especially true of this morning's trio of celebs. We spotted Rosie Huntington-Whiteley, Jessica Alba, and Diane Kruger (three celebs with some serious street-style prowess, we might add) showing off the value of a great army jacket. Rosie gave us a more tailored version; Jessica selected one by Rhyme & Echo, updated with leather sleeves; and Diane Kruger topped her everyday ensemble with a Rag & Bone jacket. Each is a testament not just to the outfit versatility of the army jacket, but the fact that it also comes in a version that's likely perfectly suited to your own style personality. Rosie gives us one that's just right for the sophisticate; Jessica offers up an edgy style; and Diane suits that sportier angle. The fact that they go with everything and can be either a perfect Winter layer or a lightweight Spring jacket just makes them a smart investment. Invest in your own with our editors' picks below.
