If you havent had any luck finding awesome 60s vintage clothes at your second hand stores, garage sales, ebay or wherever you might be looking (why were mid-century women all so short?!!) Banana Republic has kicked off its fall season with a line called "Mad About Style" that's inspired by the gorgeous looks on Mad Men.
Check out the kickass online look book then head down to see the looks styled at your local Banana. If you happen to live in SF, window after window at the Union Square store is staged with gorgeous contemporary takes on 60s Madison Avenue style.
As an added bonus, Banana is having a contest in which you can win a walk-on on Mad Men. I wonder if you get to keep the wardrobe!
