Pat McGrath Uses This Skin Combo to Enhance Sienna Miller's Pregnancy Glow

Sienna Miller just took a page out of Rihanna's playbook and made her baby bump the most stylish accessory possible. Ever since Riri broke the internet with her now not-so-unconventional maternity style, dressing while pregnant has never been the same, and Miller is the latest and greatest example.

The actor and fashion icon walked the red carpet at Vogue's Vogue World event in London in a jaw-dropping Schiaparelli dress that highlighted her bump in the chicest way possible. A two-piece dress, the top was styled like an oversized button-down that was tied just below her chest. The bottom half was made of the same material but ballooned out to form a puffy, fluffy skirt that stopped just on her knees before flowing into a pair a sheer black tights.

Miller was glowing, and while surely her pregnancy was to thank, so was her gorgeous makeup, applied by the legendary Pat McGrath using all Pat McGrath Labs products.

McGrath tells Byrdie that "Sienna Miller's pregnancy glow became the ultimate muse. Dressed in the artful opulence of Schiaparelli Haute Couture by Daniel Roseberry, her complexion was nothing less than a canvas for immortal beauty."

McGrath says that the glam process "began with the elixir of our Divine Skin: Rose 001 ($86) The Essence," Which was the first step in "setting the stage for the flawless application of Skin Fetish Sublime Perfection Foundation ($69) and the soft, candle-lit glow of our Highlighter and Balm Duo ($50) in Nude."

McGrath adds that Miller's "eyes captured the night with a stroke of Perma Precision Liquid Eyeliner ($35) and the inky allure of Dark Star Mascara ($34)." Plus, "her lips were finely outlined with Permagel Ultra Lip Pencil ($29) in Structure and filled with SatinAllure Lipstick ($30) in Nude Venus, finished with a touch of Lip Fetish Balm ($39) in Clear."

Overall, to McGrath, the effect was a "balanced, beautiful look that celebrated both her natural beauty and the majorness of event." And the "majorness" of the event is no joke. Once inside, Miller was front row for huge performers like British rap sensation Stormzy and alt-pop icon FKA Twigs and watched Naomi Campbell, Linda Evangelista, Cindy Crawford, and Christy Turlington reunite on the runway in shimmering coordinating ensembles.
