Katy Perry Channels Her Inner Cher Horowitz At 2013 MTV VMAs After-Party (PHOTOS)

Seems like Katy Perry has been watching a lot of "Clueless" lately (and we can't blame her).

The 28-year-old made us have some serious Cher Horowitz flashbacks at a 2013 MTV VMAs after-party on Sunday night when she wore a plaid pleated Alice + Olivia skirt, knee-high tights, studded boots, a leather bustier à la Madonna and a choker which had all kinds of '90s vibes.

Frankly, we kinda prefer this vintage look to her VMA outfit which saw the "Roar" singer embrace her "wild" side and channel Miley Cyrus and Madonna with a gold grill. (But hey, if Richard Simmons approves, then we can't really complain.)

But after the sun rises and the party-goers disperse, gone are the fun clothes.

Russell Brand's ex ditched her nostalgia-filled outfit for a more ladylike ensemble when she stepped out in New York on Tuesday while promoting her upcoming record, "Prism."

Oh Katy, you're such a style chameleon.
