If you're on the lookout for an off-duty yet sharp ensemble, go for a dark green crew-neck t-shirt and chinos. Unimpressed with this getup? Introduce a pair of white work boots to switch things up. This combination is also great if you're on the hunt for summer wear to get through a tedious day. Sartorial inspo like this will help you stay seriously stylish as you move through your 20s.
