Good news for those looking for a cheap way to update your Spring wardrobe: you probably have this must have in your wardrobe already. We're talking about a classic blue shirt, preferably with a stripe of some kind. We first saw this key item trickling through via the street style crowd last year, and it's showing no signs of slowing down this season. In fact, the more simple shapes of last season (off-the-shoulder, wrapover, or blouson) have been taken to new extremes, with extra sleeve details, slashes and cutouts, embellishment, or dramatic shapes. If you don't have your own blouse from last season, try raiding your man's wardrobe: voluminous sleeves and longer lengths only add to the chic factor, as these style stars show. Take a look at just a few of the ways you can wear this trend for 2017, then shop your own if you still think your wardrobe needs an upgrade!
