Definitive proof that a yellow crew-neck sweater and blue jeans look amazing when you team them together in a laid-back ensemble. Finishing off with a pair of burgundy leather work boots is a guaranteed way to bring an air of stylish nonchalance to this look. While it can be a bit nerve-racking and time consuming to stay fashionable on extra cold days, it's getups like this that prove it's quite doable. A no-brainer outfit proper for 30-something Millennial gentlemen who prefer casual clothing.
