Go for a beige blazer and a white long sleeve shirt for relaxed refinement with a masculine take. For something more on the sophisticated end to complete this outfit, introduce a pair of black leather loafers to the mix. So if you're looking for a modern but also age-appropriate outfit, this one fits the bill.
Show that you do semi-casual men's fashion like a maverick in the menswear department in a beige blazer and a white long sleeve shirt. Finishing with a pair of light blue athletic shoes is a simple way to inject a more laid-back aesthetic into your ensemble. This pairing should encourage anyone who was hesitant about donning casual outfits as a middle-aged gent.
