The entire month of December requires American Pharoah's stamina, Mother Theresa's patience, and Elizabeth Taylor's penchant for glamour. Hey, it's a marathon, not a sprint, right? So, if your calendar is full (or still filling up—have faith) rest assured that the inspiration-finding part of getting ready for any of the season's festivities is taken care of. We asked three women to style themselves for their ideal holiday scenario and write out the details for the rest of us—a bit of outfit and makeup wealth-sharing, if you will. Wrapping up the festivities in our third and final look is Sarah Chavez, Managing Editor of 25 , Anja Rubik's art magazine that's really more of a book released in very sexy volumes every year. After reading this one, look back at our previous looks to suit all of your office open bars, family obligations, and general merriment.

For me, the holidays are really about unwinding and spending time with my family. I come from a really big tight-knit family and we always have a fancy holiday party where everybody gets really dressed up. My mom is one of seven children—six girls, so it’s a big thing with 30 of us all in one place. Getting ready is always fun. I have a bunch of younger cousins and I have a little nephew now, so it’s important for me to be comfortable even though I’m dressed up. Which means...

Outfit. Elastic waistband pants! But chic. I collect vintage Japanese designer pieces and have this Comme des Garçons velvet pajama suit that’s really special. It's chill, but still elegant. I’ll wear it with these silver (Prada) slingbacks. They’re fun and give the look something extra. People probably think about doing a party dress, but this is just so much more comfortable and different. The velvet is festive with its own kind of luxe sparkle.

Nails. I love a navy polish to make the look all monochrome. This one is OPI's I Saw...You Saw...We Saw...Warsaw(haha). I get manicures every week, which the lady who does my nails thinks is too much. She says, “You can just do a polish change, Sarah, you don’t always have to do a manicure.” But it's my weekly indulgence—and I love the massage part. I like to change it up because I can't stand a nail that’s chipped or clashes with my lip color.

Skin. Since I don’t wear a ton of makeup, I’m all about how you apply your skincare. It's something I learned from Isabelle Bellis, the best facialist—a good face massage to start is key. I like doing a serum first, and I’ve been using Joelle Ciocco Mediateur Oxygenation Serum Booster. In winter, La Roche-Posay's Hydraphase Rehydrating Moisturizer works wonders. I like using Philosophy Fresh Cream Lip Scrub—it makes your lips so soft. Then I layer Glossier Balm Dotcom on top.

Face. For a party, I actually am experimenting with wearing the Balm on my lids too—an idea that came up when I wanted some sparkle near my eyes but didn't have much in terms of eyeshadow. The effect is a bit like velvet is for my outfit...low-key shimmer. On my lips, I mix MAC Lady Danger and Nars Red Square Velvet Matte Lip Pencil. Nars first all over the lip, then the MAC. It's the perfect red/orange balance. On my brows, I use Anastasia Brow Wiz in Medium Brown and then brush them up with Glossier Boy Brow in Brown. My favorite mascara for events is Lancôme Définicils Waterproof—just because my eyes always water, especially in the winter with the wind. I've been using the Glossier Perfecting Skin Tint in Medium and layer that with my Tarte Concealer that's really amazing. I’ve never used concealer until this year. I went into Sephora and asked the sales associate, ‘How do I look a bit more awake?’ The Tarte was the first one she recommended and I said, ‘Cool. I’ll try it.’ And it works!

Hair. My hair is so long, I feel like I can wear it like a scarf, particularly in the cold. I put it in a braid this morning after my shower, air-dried it, then brushed it out, and it got a bit of a wave. I use Shu Uemura Essence Absolue Oil, it protects the hair really well. One thing I’m pretty religious about is trimming my hair every three months or so, because I think long hair needs to be healthy hair—otherwise it’s like you're just holding on to length, you know? Beyond that, I don't take any heat to it and that's enough to keep it happy. Sometimes I keep the braid in—but only if I've slept on it. I never want my hair to look too precious.
