Combining a navy zip sweater with a white and black horizontal striped crew-neck t-shirt is an awesome choice for a laid-back ensemble. A pair of white leather low top sneakers can integrate well within plenty of outfits. As the weather starts to warm up, it's time to shed those heavy winter clothes and choose an ensemble that's lighter, like this one here. Ideal if you're looking for some incredibly inspiring casual style for gentlemen in their 30s.
