Well, I suppose what you're really paying for is the double striped sleeve as there are several contrast placket cardigans on the market this year. I'd say if you don't need it, hold on to that money to put towards something you've really had you're eye on for a while. Just my $.02.
Quite the valuable two cents. After a day of consideration, I've been able to rationalize why it just makes no sense to buy this thing. Aside from the fact that I already have three different navy cardigans, I hate wearing red and wouldn't be able to pair this with much.
