I judge the classiness of a restaurant not on the food on the menu, weight of the cutlery or the prices on the bill. I judge it based on how FEW of the serving staff are wearing yoga pants.
I hate the way the yoga pant trend has made the idea of "black pants" mean "that which you wear to contort your body in the name of physical and spiritual flexibility". I've seen it paired with a hoodie, a tunic, a grocery store smock, even as part of a suit.
The worst is the fact that I can't wear my black (dress) capris to work without fearing someone thinking I'm wearing stretchy athletic gear. Lululemon, I place the blame on you for messing with my once perfect: "Mix of business and casual" approach to business casual (that is: one business piece + one casual piece + one statement piece)
So believe me when I tell you, these are not yoga pants. These were once full length pants which I cropped for summer wear. They have a button and a zipper. They have three slit pockets. They have a crease down the front and require ironing.
