Such essentials as a grey v-neck sweater and blue jeans are an easy way to introduce effortless cool into your off-duty collection. A pair of brown leather desert boots complements this outfit very well. In the winter season, when comfort is crucial, it can be easy to surrender to a less-than-stylish ensemble. However, this ensemble is a practical illustration that you can actually stay toasty and remain stylish at the same time during the winter season. Great for a gentleman in his twenties if you want to project a carefree spirit.
