For a poignant illustration of what a difference 20 years can make—or why time is but a societal construct—may we direct your attention to the celebrities filing into the 2006 Met Gala ahead of the May 4 event.

From Jennifer Lopez and Marc Anthony to Tom Brady and girlfriend Bridget Moynahan (yes, his future ex-wife Gisele Bündchen was also there, posing solo), the former couples alone are wild blasts from the past.

Also hitting the steps outside the Metropolitan Museum of Art were a who’s who of mid-2000s It girls and fashion royalty, including Jessica Alba, Liv Tyler, Lindsay Lohan, Scarlett Johansson, Eva Mendes, Mary Kate Olsen and Ashley Olsen, Zoe Saldaña, Selma Blair, Kate Moss and Victoria Beckham.

They were all dressed to the nines, but leave it to Sarah Jessica Parker to be the walking illustration of the night’s theme. In honor of “AngloMania: Tradition and Transgression in British Fashion,” she delivered an instantly iconic moment twinning in red tartan plaid with Alexander McQueen.
