Teaming a navy bomber jacket with a white dress shirt is a good choice for a classic and casual outfit. As you're going from your 20s to your 30s, you probably want to start dressing like an adult man. That's when combinations like this come in useful.
For a look that's very simple but can be dressed up or down in a ton of different ways, choose a navy bomber jacket and a white dress shirt. If you need to effortlessly dress down this ensemble with footwear, why not rock a pair of white and red leather low top sneakers? If you're not sure how to dress as a man in his twenties, this pairing is a good illustration.
