Silk blouses

I have been really into silk blouses lately. I love how retro and 70s a silk blouse looks. I imagine pairing it with big gold bangles or hoop earrings. The nice thing about this one is it looks like it can be worn as either a dress or tucked into trouser pants. And it is not overly embellished. At $33 I wonder if I can find something similar for less at the thrift store.
