Go for a pink print bomber jacket and sweatpants if you want to look cool and casual without spending too much time. You can stick to the casual route when it comes to shoes by finishing off with pink athletic shoes. As the weather starts to warm up, it's time to shed those bulky winter gear and opt for an ensemble that's lighter, like this one here. This combo shows that as a 20-something guy, you have a vast array of outfit options.
