This combo of a grey cable sweater and black skinny jeans is hard proof that a straightforward casual look doesn't have to be boring. Rounding off with a pair of black leather double monks is a fail-safe way to infuse a touch of elegance into this outfit. If you're on the hunt for a killer winter-to-spring look, this just might be it. Outfits like this help welcome the big three-oh with class and enthusiasm.
