A grey crew-neck t-shirt and navy jeans are wonderful menswear essentials that will integrate perfectly within your current casual fashion mix. Our favorite of an endless number of ways to complement this ensemble is with black and white check canvas low top sneakers. Keep this look in your front hall wardrobe come warmer days, and we guarantee you'll save time trying to pick out what to wear on more than one morning. Relaxed casual combinations for teen guys aren't actually that hard, as you see here.
