Penn Badgley was spotted looking stellar and summery this week while walking around NYC with a friend. The Gossip Girl star was rocking what has to be a nearly perfect festival outfit, even though he wasn't at a festival, obviously.

Nailing the three rules of festival attire — comfort, style, and practicality — Badgley could walk right off the streets of Manhattan and into his nearest outdoor gig without having to change a thing.

He had a wicked cool striped vest (keeps you feeling fresh and airy), a battered pair of slim-fit denim shorts (hard-wearing), a decent pair of Nike sneakers (you walk for miles at festivals, so flip-flops aren't an option), and a backpack, which we'll assume contains a really nice light jacket in case it rains. Bonus points for the Wayfarers and water. Stay hydrated, dudes.
