On the podcast this week, we speak with Mats Wallin (@when_in_stockholm), a creative director at an advertising agency based in Stockholm, Sweden.    I discovered Mats while pursuing Instagram for great men’s style and found a couple outfits on his brad new account. His stark white hair and Mad Men inspired aesthetic instantly attracted me to his page and I wanted to learn more about the man behind the gram.    Today on the show I chat with Mats about his initial interest in clothes, his thoughts on a well curated wardrobe, and what inspired him to start posting his outfits on Instagram.
