Taylor Swift's Vivid 'Tonight Show' Dress: Yay Or Nay? (PHOTOS, POLL)

Should we call it the "Vogue effect"?

Taylor Swift stopped by the "Tonight Show" on Monday to charm Jay Leno and actor Michael Clarke Duncan and talk about her upcoming movie, "The Lorax."

But it was Taylor's vivid blue-and-red Tracy Reese patterned dress that we noticed first -- wow! Check out those colors!

T.Swift usually sticks with glittering gold dresses from the likes of Reem Acra or simple styles like the white dress she wore to the movie's premiere on Sunday night.

But since she served as cover girl for Vogue's February issue, Taylor seems to have upped the fashion ante, wearing a stunning red carpet gown at the Grammys and later venturing into "dustbowl chic."
