Here's another post where you can tell we're in a warm climate. But Spring is on its way so you can rock something similar very soon! In this shot Kirk is wearing a unique blue and green striped/textured button up (thrift find) over a simple, off-white T-shirt. Try wearing something similar and don't feel obligated to button your shirt all the way down. Pair with some slim fit trousers and oxfords with no socks. Alternate the pattern/color button up with a different color T or V-neck.
Texture Button Up Shirt (could easily be denim or other color! Stay away from plaid, it's too hipster for this look) - 1. Old Navy Chambray $18 / 2. Levi's (denim) / 2. Levi's (other) / 3. Nordstrom 1901 /
