This outfit shows that it is totally worth investing in such menswear essentials as a tan crew-neck sweater and navy dress pants. Complete this ensemble with a pair of brown leather loafers for maximum fashion effect. Keep this combo ready to go when warmer days are here, and we guarantee you'll save a ton of time crafting an ensemble on more than one occasion. All in all, a nice choice if we're talking fashion for 20-year-old guys.
