A few years ago, I picked up a Carhartt Men’s Loose Fit Heavyweight Short-Sleeve Pocket T-Shirt during a sale much ... from extra-small up to 5X with tall versions of each size.

Short sleeve cardigans are meant to pair with a camisole, tank top or a dressier short sleeve shirt, often with some fine detailing like lace trim, a collared neckline or a button down.
