Billie Eilish took the stage on the opening night of Lollapalooza Brazil at Autodromo de Interlagos in Sao Paulo, delivering an energetic performance of her Һit songs to her devoted fans.

The 21-year-old singer-songwriter seemed fully engaged as she showcased her talents alongside fellow artists such as Kali Uchis and Lil Nas X at the music festival.

Eilish opted for a green-and-white football jersey top paired with a striped long-sleeve shirt underneath, creating a unique look for her performance.

 Complementing her ensemble were black-and-white Air Jordan athletic shorts, matching socks, and vibrant yellow Nike high-top sneakers, adding a pop of color.

Accessorizing with sparkling necklaces and rings, Eilish styled her jet-black hair into braids cascading over her shoulders. Completing her outfit was an orange-and-white trucker cap, which she playfully adjusted throughout the show.

Meanwhile, Kali Uchis captivated the audience in a form-fitting white top that accentuated her toned arms and midriff, paired with a miniskirt showcasing her thighs as she entertained her fans. She completed her look with fuzzy knee-high boots, adding flair to her performance attire.
