For a laid-back and cool ensemble, consider pairing a blue v-neck t-shirt with navy jeans — these pieces go beautifully together. Add black leather low top sneakers to your look et voila, this look is complete. You can bet this getup will become your go-to come hot sunny days. Think you can't pull off modern off-duty outfits as you pass the big 5-0? This combination is a powerful demonstration of otherwise.
