Exactly How Belly's Beauty Look Came Together in "The Summer I Turned Pretty"

If we learned one thing from "The Summer I Turned Pretty," it's that book adaptations are always better when the author is at the helm. Jenny Han, the original mastermind behind the book trilogy the show is based on, had a clear vision for how her characters would translate on screen, especially Belly. Makeup artist Lindsay Irish-Desarno, who originally led the department at the start of filming, worked with Han to create Belly's realistic, soft makeup look.

Sall says that Tung's BTS prep always included eye patches like the Live Tinted Rays Copper Eye Masks, Supergoop! Unseen Sunscreen for her face, and Sun Bum Sunscreen Lotion for her body. As for her makeup, the team relied on the Makeup by Mario Master Mattes Eyeshadow Palette, especially the darker colors that work well as a soft liner. When they wanted a stronger eye look, they used the Stila Smudge Stick Waterproof Eye Liner in Damsel. If you really want to capture that #BellyCore aesthetic, you'll need the Burt's Bees Tinted Lip Balm in Rose and the Laneige Lip Glowy Balm in Berry.

Fans of the book will also know that Belly is a sucker for a good snack, so it's no surprise this character detail was brought to life in the show, too. Belly's treat of choice: Cheetos. So what's the pro secret behind this movie magic? "We had actual ground-up Cheeto standing by to add more onto her fingers," Sall says. "Digging around in a bag of Cheetos is still the best way to get cheesy fingertips."

Even without a first date on the calendar, we — and just about every other "TSITP" fan — have been asking Sall to reveal the lipstick Belly borrows from Susannah (played by Rachel Blanchard) for her date with Cam (played by David Iacono). "It is from the Maybelline Color Sensational Made For All Lipstick, and the shade is Pink For Me," she says. "We ended up having to buy multiples, and I searched all over for a copy and ended up finding one at the grocery store." Like Sall implies, this lipstick shade is not the easiest to hunt down, but you can still score the exact shade on Amazon.

Like real-life best friends, Taylor (played by Rain Spencer) and Belly influenced each other's makeup looks in the show. "When I was designing Taylor's look, I kept it natural, but used subtle elements to contrast with Belly," Sall says. "Taylor almost always had some kind of shimmer when Belly was more matte." For example, when Belly would be wearing a product, like Burt's Bees Lip Balm in Rose, Taylor would be in something similar, but more glossy, like Rosebud Salve. Taylor always encouraged Belly to step out of her comfort zone at Cousins; it's this influence we see permeate Belly's choices throughout the series as we watch her look evolve.

Speaking of evolution, Belly has her swan moment in the final episode at the debutante ball. Designed by makeup artist Jennifer Chavez, this look came directly from Han's inspiration: the 1968 film adaptation of "Romeo and Juliet." According to Sall, Chavez opted for products that differed from Belly's natural everyday look to give her that lit-from-within glow, courtesy of the Kosas Cream Color & Light: Crème Cream Blush & Highlighter Duo in 8th Muse and Tropic Equinox. Chavez also used the Tartelette Juicy Amazonian Clay Eyeshadow Palette to bring a satin shimmer to Tung's eyes, MAC Cosmetics Pro Longwear Fluidline Eye Liner in Blacktrack to accentuate her lash line, Dior Diorshow Brow Styler Ultra-Fine Precision Brow Pencil to polish and define her brows, and Dr. PawPaw Tinted Multipurpose Soothing Balm in Peachpink for her lips.

The volleyball scene was a win for Team Conrad (you have to dive, Jeremiah — that's why there's sand!), but the one thing we're more interested in than Belly and Connie's secret handshake is the sunscreen they used to film this scene. It took days to wrap and at least four different formulas to cover the cast. Makeup artist Shannon Kernahan even had a timer set to make sure all of the actors reapplied their SPF every hour. The team's favorites: Supergoop! Unseen Sunscreen, Supergoop! Play Antioxidant Body Sunscreen Mist, Sun Bum Sunscreen Spray SPF 50, Jack Black Intense Therapy Lip Balm SPF 25, and Supergoop! (Re)setting 100% Mineral Powder Sunscreen, specifically for their scalps. Some makeup was involved, too. To battle sweat, Sall says the team opted for Fenty Beauty Pro Filt'r Soft Matte Longwear Liquid Foundation and Tarte Shape Tape Concealer.
