"I don't want to offend anyone with bridesmaids, so I think I'm just going with my sisters," Rachel, 32, toldUs Weekly when asked which women will serve in her bridal party.
Rachel said that since she and Bryan have so many close friends, they've come up with an idea to make everyone feel special.
"My new thing is that I think we're going to have a couple of rows," Rachel explained.
"A row dedicated to the girls from [The Bachelor] and a front row for my sorority sisters. He's got the same thing, [a row for] Bachelorette guys, fraternity guys."
Rachel, who graduated from the University of Texas at Austin before earning her law degree from Marquette University, and Bryan, who is a proud University of Florida alum, got engaged on the Season 13 finale of The Bachelorette, which aired in August.
Since going public with their romance only several months ago, Rachel and Bryan have conquered difficult times together and are still trying to get settled in their new life.
"We're really just trying to, like, kind of do normal life stuff," the Dallas attorney told Us. "Like, are we going to stay in Dallas or are we going to move to Los Angeles? That's the kind of stuff we're figuring out."
"That we don't know," Rachel admitted. "We know that we want [our wedding] to be next year, we haven't like started seeking out if we want to do it on television yet."
Regardless, Rachel apparently can't wait to become the Miami chiropractor's wife. When she talked to Us last month about setting a wedding date, Rachel revealed, "Honestly, I could elope with Bryan tomorrow."
Rachel continued, "It's so funny because my mom texted me the other day and she goes, 'Secretly I would love for you to just elope.' [My] family loves him."
