Shawn, one of our very own at 9402, is wearing the men's plaid pocket button down under the ultra soft Merino V-neck Sweater. When layering sweaters like this it's important to pick colors that will compliment the shirt worn underneath. Avoid being too "matchy matchy" with the same colors on bottom and top, unless you're going for something ironic in which case you win!
This look is casual enough to be worn everyday of fall/winter, but can also be dressed up with slacks and/or a blazer.
The straight fit cords, add subtle texture to the look making it more interesting and definitely more stylish.
Being a gentleman never goes out of style (especially when you're well dressed).
