Dress in a white double breasted blazer and navy cargo pants for a sharp look. And if you want to immediately play down this look with a pair of shoes, add a pair of athletic shoes to the mix. This getup isn't a hard one to nail and it's summer-ready, which is most important when it's baking hot outside. If you're not sure how to dress age-appropriately but also look stylish, this pairing is a winning option.
