I think I heard about an "Incognito outfit" from Gala for the first time.
It's the kind of stuff your wear when you have to get out of the house for some errands but don't want to be bothered thinking too much about what to wear.
The leggings were a Christmas present from my sister a couple of years ago. They are very thick, not show-through. It's a comfy outfit for longing around, but decent enough to go out to take a walk.
