It's pics like this that make me wish that we had a tag which combined dressing and undressing rather than having them separate. It's often just too hard to tell which they're doing. In this case, given the position of her fingers, I'd say that she's pulling down on her pants, so she's dressing. And yet, the pic is tagged with undressing. Obviously the person who tagged it saw what she was doing differently. Plenty of other pics don't really have _any_ indicators whether the person is dressing or undressing. In any case, it's this kind of thing that makes me wish that the tag was something like dressing_undressing (since I'm not aware of a word in English which encompasses both). I suppose that such a tag would be rather ugly, but at least then we wouldn't have to try and figure out whether someone is putting on clothes or taking them off.
