Consider teaming a windbreaker with chinos to show you've got serious styling prowess. Balance out your ensemble with more laid-back shoes, such as this pair of grey athletic shoes. This ensemble demonstrates that even well into your 60s your style options are far from limited.
If you don't take fashion too seriously, go for a relaxed casual menswear style in a windbreaker and chinos. A pair of beige leather slip-on sneakers looks wonderful here. This getup should encourage anyone who had doubts about sporting casual outfits as a 60-something gentleman.
