Some may frown upon all denim outfits. I used to as well, until I found myself preparing for a trip on a rainy/snowy day. I needed a no-fuss, comfortable outfit perfect for flying. Enter my denim shirt. It’s doesn’t wrinkle easily and could withstand an evening’s worth of travel/napping. I’m not brave enough to wear similar denim colors head-to-toe, but this is a good start.
