A charcoal suit and a polo neck sweater are a wonderful pairing that will get you a great deal of attention. Go ahead and complement your look with a pair of beige suede espadrilles for a more relaxed touch. This outfit is a pretty savvy idea, especially for autumn, when the temperatures are dipping. If you're wondering what you should wear as a gent in his 20s, this getup is a good source of inspiration.
