A v-neck sweater and jeans are must-have menswear staples if you're piecing together an off-duty closet that matches up to the highest sartorial standards. Finishing with a pair of tan suede work boots is a guaranteed way to inject a more relaxed spin into this ensemble. This combo is a striking illustration you can still look on-trend while bundled up. A great example for anyone who's not sure how to dress at 30.
