Attraction is subjective, so there is no one outfit that is attractive on guys. However, many tend to see the white shirt, jeans and a leather jacket combo as a classic and cool look that attracts many. Another outfit that always seems to impress is a well-tailored suit. Pair your matching blazer and suit pants with a crisp shirt and formal shoes if you have an important event to go to, or opt for a white tee and sneakers to make the look a bit more casual. All of these are items that every man should already own and can be easily interchanged and paired together.
