Casual jackets are like sport coats, but actually fall under the heading of "Sportswear." You can find these versatile jackets in the classic sizes: S, M, L, and XL, rather than by chest size and dimension (42 Long, etc.) like a sport coat.
What makes casual jackets so versatile? They're less structured than your typical sport coat or blazer. You can identify a casual jacket easily – look to see if the jacket has little or no lining, and typically no padding at the shoulders. Be assured, these aren't your grandpa's old-school, billowing sport coats. Today's casual jacket tends to be a little slimmer, and comes in a variety of fabrics and textures, including cotton, corduroy, tweed, herringbone and velvet. The only limit is how many you can fit in your closet.
Your casual jacket can be all work in the daytime and all play after hours
