Melissa Rivers Wants to Wear Black Wedding Dress — Fiancé Steve Mitchel Made Her 'Promise' Not To (Exclusive)

“I'm not wearing white,” Rivers tells PEOPLE exclusively of her upcoming wedding. "But navy and dark gray are still in play."

Melissa Rivers has no plans to walk down the aisle in a big white wedding dress when she marries attorney Steve Mitchel.

The podcast host, 55, is in the midst of the wedding planning process, and while she’s still not exactly sure what she'll wear on her big day, it won't be a traditional gown.

“I'm not wearing white,” Rivers tells PEOPLE. “Steve made me promise I wouldn't wear black because I wear so much black. But navy and dark gray are still in play.”

As for other big decisions, the guest list is yet to be nailed down. Rivers added that while the couple want to keep the invitations to a limited group, it’s proving to be a challenge.

“We're not going to do something too big,” she explains. “He's had a big wedding. I've had a big wedding. This is really going to be about the people we care about.”

She goes on to joke: “Unfortunately the bare bones list is 140, so I think we have to start caring less about the people on our list.”

Rivers says she has time to think over every detail because “the wedding isn't happening until 2025.” She also joked about missing her comedy icon mother Joan Rivers throughout the planning process.

Rivers and Mitchel got engaged in October after a year-and-a-half of dating. The couple were vacationing in Mexico when he popped the question.

“It’s a big step for both for us and I’m still in complete and total shock, even a month later, but beyond happy,” Rivers told PEOPLE exclusively in November.  “And more importantly, my mom would have approved of the ring. Oh yeah, and of Steve too!”

They first met at a Didi Hirsch Mental Health and Suicide Prevention event. Rivers was an event co-chair, while Mitchel attended as someone’s guest. After began dating that Rivers — who previously swore that she’d never remarry after her 2003 split from ex John Endicott — decided she was open to the idea.

​​“All of my friends are joking that I had a pretty good run and almost got to the finish line of staying single for the rest of my life. It’s something that I never believed in my heart of hearts that I would ever do. But, apparently hell freezes over and pigs do fly,” she says, jokingly adding, “I didn’t see it coming and it’s really not easy to pull a fast one on me. Once Steve shoved some smelling salt under my nose from passing out, I said yes.”
