Christina Aguilera, 45, Goes Full ‘Dirrty’ in a See-Through Minidress and Lace Bra

Christina Aguilera has not forgotten how to be “Dirrty.” The 45-year-old singer hit the carpet at MISTR’s second annual National PrEP Day party at The Abbey in West Hollywood on Saturday night, October 10 — and InStyle reported she wore nothing under her sheer mesh minidress except a black lace bra and lace-up leather underwear.

The dress itself was a black sleeveless tulle minidress covered in black crosses, a look InStyle called a gothic-glam twist on the naked dress. Underneath, the plunging black lace bra had a dangling silver charm at the bottom of the underwire, and her high-waisted, cheeky black leather panties were laced up each side with silver grommets. She went pantsless, bared her midriff, and finished with dramatic over-the-knee boots that the Daily Mail said showed off her “ultra tiny” waistline.

CelebMafia’s style desk noticed the details: the crosses varied in size and decoration across her torso, narrow strips fell from the hips and thighs, and the thigh-high boots alternated diagonal black bands with transparent sections down her legs — so the peekaboo effect ran from bust to boot.

Aguilera — who, per the Daily Mail, recently revived Lady Marmalade on its 25th anniversary for a beauty ad — had plenty of company. Just Jared reported Charli XCX, Kesha, Demi Lovato, Chappell Roan, Kim Petras and Tove Lo all turned out, along with Emily Ratajkowski, Bella Poarch and Real Housewives stars Phaedra Parks, Meredith Marks and Sutton Stracke. Charli even took the stage, performing “Club classics,” “360” and “Von dutch” from Brat.

The party had a point beyond the outfits. MISTR, a telehealth platform, held the night to raise awareness about HIV prevention and access to PrEP. “Healthcare should not require you to edit yourself first,” MISTR said, according to Socialite Life — and CEO Tristan Schukraft, who also owns The Abbey, has previously said: “We know how to end new HIV transmissions in the United States. The tools exist. The infrastructure exists. What remains is commitment.”

Scoop’s verdict? Dress: see-through. Bra: lace. Shorts: laced. Christina Aguilera just proved the “Dirrty” era never really ended — it simply got a good cause.
