You'll be surprised at how easy it is to get dressed like this. Just a v-neck sweater worn with tobacco dress pants. Black leather loafers tie the look together. Modern and age-appropriate for a 20-something man, an ensemble like this will help outshine any of your fellows.
If the occasion calls for a sophisticated yet cool menswear style, consider wearing a v-neck sweater and tobacco dress pants. For times when this ensemble appears all-too-perfect, tone it down with a pair of red leather low top sneakers. As a 20-year-old heading into your 30s, this is how you dress as a grown man.
