I could not justify spending as much as alternative clothing stores charge for their cardigans. I really like the bright and embellished rock a billy cardigans you can buy but they are not cheap.
So I set out to buy a plain black cardigan. Kmart were selling them cheap. It's a nice light cardigan that's comfortable when it is cool but not cold.
For under $10 in extras I turned a boring black cardigan into an interesting rock a billy cardigan that did not cost me a fortune. I cannot remember what I paid for the cardigan but being kmart I would guess it was around $10. My cardigan is also unique which is a bonus.
