Fashion Advice Needed - Can I Wear This?

At Costco to day I saw a Kenneth Cole down parka vest in a chocolate brown. I've been wanting a down parka vest in chocolate brown (though the plum one in the picture? Could totally make me change my mind.


This particular parka vest is only $19.99. My hesitation? How do I wear it? Like in the picture with a tight shirt and jeans? Can I mix it with cords?

I'm not 25 anymore and I don't want to look like I'm trying to look 25. So, please help me put an outfit together so I can go back and buy it today before the Costco phenomenon takes effect (eg buy it when you see it or it's gone!)
