Christina Aguilera and Charli XCX brought lingerie-inspired dressing into the spotlight at the National PrEP Day celebration in West Hollywood, embracing sheer fabrics, visible underwear and revealing details. Aguilera stepped out in a sheer black mesh minidress adorned with cross motifs, while Charli XCX paired a transparent ruffled top with a black lace bra and microshorts. Tinashe also joined the evening's fashion showcase, offering another take on lingerie-inspired dressing. Her look added to the variety of sheer fabrics, lace and revealing details on display at MISTR's National PrEP Day celebration. Their outfits offered striking examples of the peekaboo lingerie trend, which turns traditionally concealed garments into deliberate elements of an ensemble.
Held on 10 October 2026 at The Abbey Food & Bar, the celebrity gathering brought together musicians and other familiar faces to raise awareness of HIV prevention and access to pre-exposure prophylaxis, commonly known as PrEP. Hosted by MISTR, the event marked the organisation's second annual celebration in West Hollywood.

Christina Aguilera Makes a Statement in Sheer Black
Aguilera embraced dramatic sheer dressing in a black mesh minidress decorated with cross motifs. Beneath the transparent fabric, a black lace bra and lace-up leather underwear created a layered look that placed lingerie-inspired pieces at the centre of the ensemble.
The contrast between the delicate mesh and the darker embellishments gave the outfit its distinctive character. Rather than keeping the underlying garments hidden, Aguilera made them an integral part of the overall look, illustrating how lingerie can move beyond the bedroom and into statement eveningwear. The combination of transparency, lace and leather also gave the outfit a bold, gothic-inspired edge, setting it apart from more understated interpretations of sheer dressing.

Charli XCX Puts Her Own Spin on the Trend
Charli XCX offered a different take on peekaboo lingerie, wearing a sheer black ruffled top tied across the chest over a black lace bra. She paired the top with black microshorts featuring a lace-up detail on one leg, bringing together revealing silhouettes and decorative accents.
The visible bra was central to the look, while the ruffled top added texture and a sense of movement. The microshorts reinforced the outfit's daring proportions, creating an ensemble that combined lingerie-inspired styling with a contemporary, unconventional approach to eveningwear.
While Aguilera's look relied on cross motifs, mesh and leather details, Charli XCX's outfit used ruffles, lace and a more abbreviated silhouette. Both demonstrated how visible undergarments can become a deliberate styling choice rather than simply remaining concealed beneath clothing.
What Is the Peekaboo Lingerie Trend?
Peekaboo lingerie styling incorporates traditionally concealed garments into an outfit through sheer fabrics, mesh panels, lace details and strategically placed cutouts. Bras, corset-inspired pieces and underwear can become visible layers, adding contrast and texture to an ensemble.
Aguilera's sheer mesh minidress and visible lace lingerie, alongside Charli XCX's transparent top and exposed bra, illustrate two ways to approach the aesthetic. One relies on dramatic embellishments and contrasting materials, while the other combines ruffles, lace and microshorts for a more unconventional silhouette.
Together, the looks highlight the defining feature of peekaboo lingerie: making underwear-inspired elements an intentional part of an outfit. Through sheer layers, visible lace and contrasting textures, the approach challenges the traditional distinction between underwear and outerwear.
