Faux 40's Sweater

I popped into my favorite faux vintage store today, Forever 21, and came across a gem - a cable knit sweater that looks straight out of the late 30's/early 40's! The medium looked about like this on me - okay, but a little slouchy, so I sized down to a small to get the cute short sweater look. In person it's a nice deep blue-red - the only shade of red I can even attempt to wear next to my face!

 

What do you think - could it be out of this knitting book?
