Wow, look at my main man aztec coming up with the caps almost immediately! Awesome work as usual.
I was looking through videos from Despierta America but didn't see much to confirm Karla's thigh highs, but those caps are pretty great.
Despierta America's Facebook site also posted some photos of Karla dressed in her "80's Businesswoman" costume today:

I tried to clean them up a bit and highlight her thighs, but the original photos from Facebook just aren't very high quality so it wasn't as revealing as I hoped it'd be:

Still, it's really awesome that Karla chose to dress like that. Karla's kind of funny in that sometimes she dresses extremely conservatively, but every once in awhile she'll bust out a very sexy outfit. She's hard to predict in that way.
I only wish we had some clue as to whether they were hold-up thigh highs with the elastic tops, or she went all the way with the look and wore a garter belt.
American TV presenters could take some tips from Italian presenters:
