If you thought all the Emmys fashion train stopped at the red carpet, you're sorely mistaken.

The celebrity arrivals at the 76th Primetime Emmy Awards certainly didn't disappoint, but many of the stars swapped their looks for the ceremony's afterparties, opting for something a little more relaxed — but no less impressive.

Palm Royale star and award presenter Allison Janney managed to channel Old Hollywood into both of her looks, trading her voluminous black-and-red gown for a sparkly champagne-colored number.

Fellow attendees like Ayo Edebiri, Kristin Wiig and Rita Ora also used the afterparties to flex their fashion range.

Ahead, see all the jaw-dropping outfit changes from the 2024 Emmys.
