The holidays are upon us and that can only mean one thing: It's time for the annual Victoria Secret Fashion Show.

It recent years, VS has amped up the televised production to include even glitzier costumes and, of course, musical performances. Last year featured the vocals of Bruno Mars, Rihanna and Justin Bieber, while this year's roster includes Taylor Swift and Fallout Boy.

Filming of the sparkliest fashion show (like, ever) has been going on all day (Nov. 13) but thanks to Twitter, we won't have to wait until the December airing to see what Taylor wore to perform.

From what we can tell, TS has at least two outfit changes. One is typical Tay-Tay: Sparkles on sparkles. The second, however, looks like a British take on Uncle Sam. We can only hope she doesn't cop another British accent, a la the Grammys.

Too much perfection in one photo! And those legs!!!
