Why not wear a white crew-neck t-shirt with navy jeans? Both of these pieces are super comfortable and will look awesome combined together. Finishing with tan suede slip-on sneakers is the most effective way to introduce some extra fanciness to this look. This combo is a winning option if you're scouting for a great, summer-ready combo. Those who wonder whether you can still pull off cool casual style as you move into your 50s, this outfit should answer your question.
