For an ensemble that's super simple but can be smartened up or dressed down in plenty of different ways, try pairing a mock-neck sweater with jeans. Get a little creative when it comes to shoes and throw in a pair of white leather low top sneakers. If you're in search of a knockout look that will take you from winter to spring, this one fits the task well. Ideal for a younger man if you want to present a carefree spirit.
