She hasn’t graduated from high school – High School Musical, that is – but KayCee Stroh is well on the way to planning her dream wedding.

“I have an absolutely wonderful wedding planner who’s [stopping] me from being a Bridezilla,” the Disney franchise’s pop-and-lock girl tells PEOPLE. “I’m so excited. It’s great. It’s going to be a January wedding. A lot of red, white and silver – and cranberries.”

The 24-year-old – who’s engaged to Ben Higginson, also 24 – is still in the process of finding the perfect wedding gown. “We’re still working on a designer for the dress,” Stroh said at Tuesday’s Cheetah Girls One World premiere in Hollywood. “I’ve got a few people … All I can tell you is that it’s going to be outrageous.”

Higginson, who owns a Utah production company, proposed to Stroh in May. Since then, he’s been an unlikely source of planning help.

“He helped me pick the flowers – most guys don’t do that,” said Stroh, who wrapped High School Musical 3: Senior Year earlier this summer. “He’s great. Surprisingly, he’s been there every step of the way when I’ve needed him … He is perfect!”

So will Zac Efron, Vanessa Hudgens and the rest of the Wildcats get invitations? “Of course!” she said. “Everyone is invited. It’s going to be a big wedding.”
