A tan crew-neck t-shirt and a grey suit are an easy way to inject a touch of manly refinement into your day-to-day wardrobe. Infuse a more relaxed touch into your ensemble by finishing with a pair of athletic shoes. Entirely appropriate for hot weather, you can wear a variation of this look all season long. This pairing illustrates that dressing your age and looking stylish are not mutually exclusive things for a gent in his twenties.
