Minutes before hosting a holiday soiree with Amazon, bright stars Kyle Richards and Kathy Hilton are sitting in a dimly lit back room in Brooklyn's 74Wythe.

The Tuesday night crowd is buzzing with anticipation but the sisters, who are warm and welcoming, openly discuss that they're only in town for a few more hours (Hilton's daughter Paris will be married Thursday). Still, with the clock ticking, the duo is dressed to the nines, with just enough time to provide a blueprint on their holiday dressing do's and don'ts.

We spoke to Real Housewives of Beverly Hills stars Kyle Richards and Kathy Hilton about everything you need to consider when picking a holiday outfit—and what you should avoid wearing when attending holiday parties.

What to consider when picking a holiday outfit

"When we do a holiday or a dinner, we tend to be more elegant," explains Kyle.

"And, when we have people over, we expect them to [also] dress up," adds Kathy. This style standard dates back to their childhood where their mother "always, always [expected them] to be dressed up elegant and nice." The two have passed this standard down to their own daughters, with a few modifications.

"Certainly, eight or nine years ago, the ties loosened," says Kathy. While their mother might have been in favor of traditional outfits (ties, formal wear), the Real Housewives of Beverly Hills co-star isn't one "for themes." Instead, she focuses her attention elsewhere.

"We tend to let people wear what they want to wear so they don't feel uncomfortable." And while Kathy is all in favor of "dressy dresses," Kyle makes it clear: "There are l-e-w-k-s, and then there are looks." Don't show up in anything low-cut or too revealing.

For the pair, collaborating with Amazon was a seamless fit. Both highlighted a selection of timeless yet trendy pieces you can get on Amazon that are perfect for the holiday season. Each found dozens of holiday wardrobe staples, all fitting for not only Thanksgiving and Christmas, but any celebration (Kathy even found elegant pieces to gift Paris's bridesmaids).

Though getting invited to a Hilton-Richards holiday is pretty exclusive, here are 10 things you need to create your perfect holiday outfit for 2021, according to Kathy Hilton and Kyle Richards.

1. This modern must-have: Lucite rings

According to Kathy, "these [lucite] rings are [the ultimate] stocking stuffers." Follow her lead by wearing them on your knuckles to add a pop of color to your holiday outfit. Because they're lucite, they're very modern-looking, Kathy says, so you can stack them and wear them for years to come. This particular set comes in a 10-pack, so you can pick and stack your favorites.
