For a casually stylish getup, go for a double breasted blazer and charcoal chinos — these two items work beautifully together. Finishing off with a pair of black leather casual boots is the most effective way to inject a more relaxed aesthetic into your outfit. So as you can see, this combo is a really smart pick, especially for in-between weather, when the temperatures are dropping. As you're going through your late 20s, you want to start dressing more professionally. That's when ensembles like this are a tested option.
