People in the Pacific Northwest don't really dress up. Ever. I am ashamed to admit that I have seen people who have worn jeans and sandals to weddings. To weddings! Come on people. But at the same time, while you want to look nice, you don't want to look out of place. I like to pair a blazer with a t-shirt and dark blue jeans to look put together, but still casual. You look nice enough to go out, but still casual.
What's a polished but casual look you like?
