During a fun game of "Happily Ever Farber" with hosts Katie Krause and Deidre Behar, Slater revealed the hilarious items she plans to take with her on their special day. Her No. 1 must-have? Vodka!
"I want to cheers to everybody's health -- I want to take a shot of vodka and then you finish it off with pickles," the 27-year-old British dancer joked. "A pickleback! It's very popular in Russian culture."
"Sasha's Russian, which is why I'm coming up with all this Russian stuff," she further explained. "You Mazel Tov and you cheers to health and happiness and speeches -- that's a must-have. I must have speeches from everyone. I will not compromise on that, and they need to be creative. Like, I don't want, you know, 'Have a wonderful life' -- give me something creative! I want camera in your face, give me a poem, anything."
According to Slater, she and Farber already have a star-studded bridal party lined up, who will undoubtedly be helping out with those entertaining speeches. Fans of the cute couple can expect to see fellow dance pros Brittany Cherry, Lindsay Arnold, Witney Carson, Derek Hough, Jenna Johnson, Hayley Erbert and Mark Ballas by their sides as they say "I do."
So where's all of this going down? "If I was to pick? Beach," Slater revealed, before switching her answer to the "woods" or "next to a river."
"[It will be] casual, yeah, I want it to be a party more than anything," Slater exclaimed. "I want everybody to be there and I don't want it to be like, 'stressful bridezilla, oh my god, she's a nightmare.' I want to be happy and to turn up and for everyone to be smiling and be partying."
And that's exactly why Slater says she's planning to "audition Russian or Armenian bands." Clearly, she wants the best of the best! "I'm a little bit tacky, we both are," she joked. "I want disco - give me like cheese and tacky and folk."
Although Slater has yet to say "yes" to the dress -- it's only been nine days since Farber popped the question! -- she told ET she already has a dream gown in mind.
"I would like, I think, fitted but lace traditional," she said. "I don't want to give away too much, but I definitely want to do not too sexy. Tasteful -- tasteful elegance I'll say."
As far as the catering goes, Slater says that between In-N-Out Burger and filet mignon, she'd have to go with the latter.
"I'm not a big meat eater. I don't do fast food really, [but] Sasha would love In-N-Out," she dished. "But he's more of a Burger King person. But umm, I think [we'll go] classy [with the food]."
Slater also revealed that the two are planning a 2017 wedding. "We definitely want at least a year engagement," she confirmed, adding that 2018 "just feels so far away."
One thing she's not too sure of? Whether her and Sasha will go all out and bust out their DWTS moves during their first dance.
"We haven't even talked about that [yet]," Slater, who said she'd love to "plan some surprises," explained. "You know, it's funny, I don't think that we will [perform]. And if we do, it's not going to be like [serious] -- it's going to be cheesy."
She is, however, hoping DWTS host Tom Bergeron will officiate, with season 19 mirror ball trophy winner Alfonso Ribeiro playing MC.
"[Tom] will do the best job," she gushed. "Tom Bergeron is going to be the best person to marry us. If it was Alfonso, it would probably take about an hour -- very chatty -- but he's the perfect MC."
