Base layer as outerwear.
I've never owned anything by Stoic, but thought the styling was great. I know that it's supposed to be a base layer piece, but I've been wearing it with jeans. It's warm and comfortable and I've gotten lots of compliments on the look. I'm 5' and 105lbs, the XS works well, though I have wide shoulders and monkey arms. There was a little shrinking after a few washings, but still fits fine (tight). However, the side zipper set off the TSA scanner at the airport. Still, I love this shirt and have bought 2 more Stoic 150 tops.
