After putting on a veritable makeup clinic here for Fall that included a lesson on tricolored eyes with splashes of orange, purple, and black, Pat McGrath shifted her attention due south of models’ lids for Miuccia Prada’s Spring show. “It’s a bold, bold, bold red lip,” she said of the matte crimson color she traced around mouths. “It’s all about a passionate woman [this season] and you can’t get more passionate than red.”

Building a flawless complexion with a slight highlight on the high planes of the face, McGrath groomed brows, adding a brown pigment through the eye socket and tracing the upper lash line with a stroke of shimmering white shadow. Then she focused on pouts, which were rimmed with CoverGirl LipPerfection Lipliner in Hot and filled in with its LipPerfection Lipcolor in the same shade. “It’s all about oversized,” she elaborated, keeping the color slightly outside of the lip line and drawing a white, “illustrationlike” curve along the cupid’s bow. “[It] makes them appear bigger,” a well-educated Jessica Stam pointed out of the animated element’s effect on her own lips, showing off some impressive know-how gleaned, no doubt, from years of enrollment at McGrath’s backstage beauty school. Lashes were simply curled and left sans mascara, while toes got two coats of CoverGirl’s Outlast Stay Brilliant Nail Gloss in Ever Red-dy and Reliably Red, which peeked out of the rare pair of flat or platform sandals that came down the runway without a set of socks (only Miuccia Prada can make sandals and socks look cool).

Guido Palau injected a touch of “tomboyishness” with a series of classic French twists that he deliberately made more “broken.” Busying his team with the task of blow-drying models’ hair straight with Redken Thickening Lotion 06 Body Builder to create a base level of texture, Palau himself took on the task of twisting individual updos on individual models like Guinevere Van Seenus, whose strands he gathered straight back, spritzed with Redken Quick Tease 15 Backcombing Finishing Spray, and then pinned up, letting the ends hang over her forehead like makeshift bangs. “Designers always want fringe, but they don’t want to use fake fringes,” he explained of the deceptive technique. “[They] want a girl with character,” he elaborated of Miuccia Prada specifically, pointing out that no matter the sartorial order—”there was a Japanese stroke,” Palau acquiesced of today’s collection—”it’s always Prada.”
