IMO this one is actually a bit more flattering than how they've looked in other moments, especially compared to this:
Maybe her shin/lower leg/below-the-knee area [and knees themselves] looks worse without her relatively thin thighs overall. Or maybe they actually look worse when she shows them together in shorter skirts and dresses... oddly, my eyes can't really tell. Luckily her beautiful face and nice upper body make up for it most of the time.

I will totally submit myself to test the hypothesis. From HW to LW my calves are always sculpted (the nice word for it, really) and my ankles are SO weak. I have to do ankle exercises every night if I don't want to wake with my ankles pain free. If I go out drinking? I'm for sure rolling an ankle. I can't even do my favorite exercise right now- running- because my ankles have gotten so bad.
