We never need an excuse to revisit one of the greatest cinematic masterpieces of our time, "Clueless." But since it is the movie's 17th birthday this year, "Good Morning America" and Entertainment Weekly decided to include the show in its "All-Star Reunion Blowout" series, reuniting Cher, Dionne and the rest of the cast (except for Paul Rudd -- cue the sad faces) for an on-air nostalgia fest.

Luckily "GMA" grilled the cast on all the topics we care about -- namely, that memorable '90s fashion and what the actors think about it today. "That hat!" giggles Stacey Dash (Dionne) when shown her giant black and white topper from the beginning of the film. "I thought it was very fashionable. I felt like Audrey Hepburn,” she said.

When presented with a picture of his erstwhile skater 'do, Breckin Meyer (Travis) quipped, "That wasn't because of the movie. I was just greasy and filthy when we made the film -- that was it."

And when asked whether she liked her many iconic outfits, particularly those plaid schoolgirl uniforms, Alicia Silverstone (Cher) replied:

"I did. But I didn't understand fashion at all. I had to do 60 changes, I was so tired and I didn't understand why I had to keep having fittings. And so I kind of hated them then... and then when I saw the movie, I was like 'I understand!'"

Thanks goodness, because we can't imagine a "Clueless" without Cher's endless wardrobe. Where else would we learn our many fashion lessons (see below)?
