A white and black horizontal striped long sleeve t-shirt and black skinny jeans are a nice outfit formula to have in your casual sartorial arsenal. The whole look comes together if you complement this getup with a pair of red and white canvas high top sneakers. This getup is a foolproof option if you're scouting for a great, summer-friendly getup. Relaxed combinations for 20-somethings aren't actually that hard, as you see.
