When the weather is unpredictable, one of my FAV pieces to pull out is this camo jacket from my military days. The gortex jacket is wind and rain friendly AND super warm, yet light as a feather. And although it isn't the most flattering jacket in the world, I still LOVE it and continue to wear it without the matching pants off course.

Outfit Combo: sweater: Zara (men's), shorts: Forever 21 (similar), tights: H&M, boots: Sam Edelman Empire, jacket: GI (gov issue from military days), and bag: Gucci (old)
