Billie Eilish’s Y2K-Inspired Shorts Are Completely See-Through

Leave it up to Billie Eilish to go against the status quo with her signature sense of style. On Aug. 15, the 21-year-old continued her obsession with the Y2K aesthetic while performing at the Sziget Festival in Budapest, Hungary. In true Billie Eilish fashion, she took the stage in a black oversize jersey that read “FAMOUS” along with the number 99 and chose the most unconventional bottom – a pair of red mini dolphin shorts layered over see-through black biker shorts and sheer tights. She slipped on red, black, and white striped socks with a classic pair of Air Jordan 3s – originally released in 1988 – further accessorizing with a red skull-printed beanie, long fingerless gloves with black and white stars, and a variety of silver jewelry.

Eilish’s latest look stays true to her well-known reputation for unusual outfit combinations, specifically embracing trends from the ’90s and early 2000s. She’s fearlessly rocked short shorts multiple times, from the tiny camouflage booty shorts she wore over fishnet tights for an Instagram photo shoot to the sheer biker shorts she sported in a similar photo dump. The young star has experimented with other Y2K trends, including a pleated schoolgirl skirt over baggy pants, oversize graphic tees and Moon Boots at the gym, and pinstripe oversize shirts, which she confidently sported at the “Barbie” premiere last month.

The “Happier Than Ever” singer has also explored other style eras and aesthetics. Recently, she channeled the ’50s in a yellow A-line shirtdress for the “What Was I Made For?” music video and her inner “soft girl” with a blue floral ruched dress by Yuhan Wang for Easter. Eilish has even hopped on the naked-dress trend with a sheer black minidress for her Eilish No. 2 fragrance campaign and a Simone Rocha lace gown at the 2023 Met Gala.
