Eighties outfits? Appearances by Penélope Cruz, Miley Cyrus and Liza Minnelli? Little by little, the secrets of the sequel to the Sex and the City movie are leaking out, and style guru Patricia Field is filling PEOPLE in. WARNING: SPOILERS BELOW.

So what was the real story behind those ’80s outfits that Sarah Jessica Parker and her three pals were dressed in – and widely seen in photos from a shoot on the streets of the Big Apple?

Flashback Time
“It was in the beginning of the movie,” Field explained. “Carrie was waiting to meet her girlfriends and she was thinking about when she first moved to New York in the ’80s and how she met Samantha and Charlotte. They’re all, in real time, meeting to go shopping. And in her flashback time, she is thinking of when she first met each one of them.”

What’s with the guest appearances by Cruz, Minnelli and Cyrus? Cyrus recently filmed a scene with Kim Cattrall, where the two ostensibly showed up to a movie premiere in matching outfits.

“That’s in the story line, but I’m not going to tell that one,” Field teases. “But, it’s fun. Miley’s a very good character. She’s a really nice girl. She’s happy and with it! She’s a very cool girl.”

Road to Morocco
What about the films’ increasingly exotic locales? After all, in the first movie, Carrie and friends fled Gotham for Mexico after Mr. Big stood her up at the altar. The new movie doesn’t disappoint, Field promises, saying they’ll be visiting Morocco.

“[We're shooting] there for about six weeks,” she said. “You’ll probably see belly dancers and Bedouins!”

But Field zips her lip when it comes to the biggest question of all: Will Carrie be expecting a baby?
“I don’t know,” she says. “You’re going to have to see for yourself because then what’s the fun?”
