On Monday, hundreds of A-listers descended upon upper Manhattan for the Metropolitan Museum of Art’s annual Costume Institute Gala. Fashion bloggers and critics have had their say, and the best and worst dressed have been crowned, but when an event is this confusing, some questions will remain. Here's what we're still wondering.

What exactly was this?

Why was there so much TopShop?

This year's Met Ball celebrated American couture (technically one couturier in particular, Charles James). When we think couture, we think old school atelier fashion, the dying art of the hand-sewn dress. So when Kendall Jenner, Zoe Kravitz, Chanel Iman, Jourdan Dunn and Toni Garrn opted for a whole bunch of boring off-the-rack dresses, it left us underwhelmed. Ugh, millennials.

Is Kirsten Dunst in the new Star Wars movie?

Surely the only explanation for that dress was to reinvent the casting announcement.

Are models the only ones who can pull off Marchesa?

Perhaps the wrinkled fabric of Katie Holmes' dress was intentional, or maybe, as the Fug Girls say, she left her dress "wadded up" in her closet, but … yikes. See also Kylie Minogue's white dress – the gold leaf isn't doing her any favors. But take one look at Karolina Kurkova, and that's a dress. Marchesa: actors and singers are people too!

Are celebrities and fashion designers actually friends?

The Met gala slideshows are peppered with pics of celebs and designers standing together (very closely) which makes us wonder: are these people actually pals? Do they hang out away from the red carpet? Does Kristin Wiig make jokes with Alexander Wang? Does she call him Alex?

Has fashion embraced underbutt?

For a red carpet event, Beyoncé made a cheeky appearance.

What the hell is “ball fashion” anyway?

Clearly no one had any idea how to dress for something most commonly depicted in animated features from the 1990s (although Beauty and the Beast would be a great theme for next year).

Sarah Jessica Parker and Benedict Cumberbatch were on the same page, considering it an opportunity for prom hair and watch chains. But Cara Delevigne looked great in trousers. And Erykah Badu had that hat.

Proposed rule: if there isn’t going to be waltzing, we shouldn’t call it a ball.
