This is the first Cardigan sweater I have found that I am able to wear during the winter months.  Most Cardigan sweaters are light weight and are usually worn for looks. This black button down Cardigan is perfect to wear over winter sweaters or shirts. It also comes with a belt to go around your waist or you can wear it as a bow around your shoulders and neck. I am 5'1" 114 lbs. and I got a small. It actually fits me better than I expected. The quality of this sweater is also better than I expected. I will be wearing it for many years to come. Need a heavy Cardigan sweater for the winter, I suggest you look at this one.
