I wore these black legging-esque pants because they're just as comfortable as leggings but can pass as pants, and layered a flannel over a henley for warmth. So while I wasn't as productive as I should have been, at least I looked a lil more put together than just leggings and a sweatshirt! My priorities are clearly in order here.
Flannel- LL Bean
Boots- Enzo Angiolini (Nordstrom)
