Here is a knit cardigan with a open breasted collar. This sweater is made of cotton and polyester materials. There are striped accent details on the collar and sleeve cuffs. Try wearing a slim-fit dress shirt underneath with slacks or jeans on the bottom to create a semi-formal outfit. Wear a plain solid v-neck underneath with jeans to change it up for a casual look! Lastly, pair it up with your favorite shoes to complete the look.
