Argentine actress Agustina Palma chose a feathered black mermaid gown by three-time Emmy winner Birgit C. Muller for the Las Vegas red carpet, where the look drew attention from the fashion press.
Las Vegas, November 12, 2026. On a Latin Grammys red carpet where white was everywhere, Argentine actress Agustina Palma chose black. She arrived at the 27th Annual Latin Grammy Awards at the MGM Grand Garden Arena wearing Birgit C. Muller Couture. The strapless mermaid gown paired a feathered bodice with a narrow band of beadwork and a pleated skirt that caught the light.
The look drew the attention of the fashion press. According to the atelier, Spain’s Clara magazine named it among the evening’s best looks, highlighting the contrast between the feathers and the sparkle. Palma wore her hair half up and chose natural-looking makeup. The atelier also noted that Mexico’s Eje Central included her on its best-dressed list alongside Rosalía, Karol G and Ana de Armas.
A rising star in Birgit C. Muller’s eyes
Muller and Palma have known each other for more than a year. The Las Vegas gown was the latest in a series of looks the designer has created for the actress.
“Agustina is a rising star. She has that rare presence that reminds me of the great screen actresses, and I love seeing her bring Old Hollywood glamour back to the red carpet in my designs.”
Birgit C. Muller
Muller has spent three decades in Hollywood costume design, working on studio films and spending ten years as head costume designer of a CBS drama. For her custom gowns, she starts with the wearer’s proportions and presence, and the occasion that brings them together.

The Disney series O11CE and Bia introduced her to a generation of Latin American viewers. She later played Valeria Delger in Máxima, the drama about the queen of the Netherlands.
Now based in Los Angeles, Palma has appeared in a Bad Bunny music video and released her debut solo single, “Mujer Valiente,” in 2025. She also attended the Hollywood premiere of Wuthering Heights in 2026.
