If you're on the lookout for a relaxed yet stylish outfit, choose a tan crew-neck t-shirt and navy and green chinos. For a dressier vibe, complement this look with a pair of casual boots. This look isn't a hard one to create and it's summer-appropriate, which is more important when it's blazing hot outside. Dressing inspo like this will help you remain incredibly fashionable well into your 40s.
