Stand Alone Sweater
While a smooth, fine cardigan can be worn layered or under a sport coat, the chunky, textured type are really meant to layer last. Logical as the textural interest and weight act the same as a sport coat - just relaxed. This cardigan is a perfect example, complete with shawl collar. Not too heavy, not too light, just right.
||Is it OK to wear a cardigan over short-sleeved shirt, such as a polo? If it's made of cotton, why not?
