A beige cable sweater and navy chinos are wonderful menswear essentials that will integrate nicely within your current casual collection. And if you need to easily play down your outfit with one item, why not introduce a pair of blue athletic shoes to your look? When temps are falling and fall is setting in, you'll love this outfit as your uniform for unpredictable fall weather. When it comes to casual outfit ideas for maturing gents, this getup looks cool on most gentlemen.
