I Knew Something was Missing

Now I'm actually a 100% sure one whole box of winter clothes is missing. Three pairs of black leggings and a pair of caramel colored skinny cords are definitely missing. And I know for sure that I didn't get rid of any of those. This weekend it will be scavenger hunt at my house in hopes of locating the missing box. I mean, how far can it really have gone? Worst part is that I have already looked through the whole house, including basement and attic. I don't know where to start...or should I say continue.
