American Apparel socks, Vanishing Elephant shirt (2011), Vintage knit, H&M sweat.
I usually pair that with my gray New Balance 574s. It is my favorite outfit right now, since the weather is aroud 14-16'C degrees in mid-september. The VE shirt is light while the knit is kind of heavy and super snug, so I don't comprise being outside or inside, it's like having a heat balance. Ok now, run to your H&M and get those sweatpants. They are so soft and comfortable, but most of all, the fabric doesn't look like you're walking out in your homewear. Those are kind of slim fit but I tighten them a little bit for a more fitted look.
