The color of half of Lizzo’s dress here is holiday-adjacent: forest green. If bright green and red isn’t your jam, try something like this.
But if you do like wearing those colors, a simple dress, like the one Idina Menzel wore to her Hollywood Walk of Fame ceremony in November, will do the trick. (That being said, Idina Menzel can and should wear whatever the hell she wants to a holiday party—and if someone complains, she can say, “I gave you, ‘Let It Go.'”)
The same goes for Kristen Bell (a.k.a Princess Anna). A crisp white dress like this is on theme for a holiday party. The colors you can just wear and have that be enough: red, green, white, and gold.
Bold, neutral patterns also work for a holiday party. People will be too mesmerized by your cheetah print dress to see you’re not wearing anything festive.
Ms. Tisdale applied this rule, as well.
As did Brenda Song.
The How to Get Away With Murder star’s dress is formal enough that anyone who called her out for not being on theme would be a monster. That’s another good strategy: When in doubt, just put on the outfit you wore to your last wedding. Unless that wedding was yours, of course. Don’t show up to your office Christmas party in a wedding gown. (Actually, now that I think about it, please do.)
