A white and black crew-neck sweater and white jeans are must-have menswear elements to have in the casual part of your wardrobe. For something more on the cool and casual side to complement this getup, introduce white athletic shoes to the mix. As the weather begins to warm up again, it's time to shed those bulky winter layers and choose an ensemble that's lighter, like this one here. And if we're talking casual fashion for young gents, this combination is ideal.
