This combination of a green-yellow crew-neck sweater and skinny jeans is irrefutable proof that a safe casual look can still be really interesting. All you need now is a great pair of low top sneakers to round off your getup. So if you're in search of a look that's seriously stylish but also feels entirely spring-appropriate, look no further. Think middle-aged gents can't pull off edgy casual outfits? This pairing should prove you wrong.
