The Austrian Who
Dressed Hollywood

Her story begins, as many of fashion's most singular stories do, not in a design school studio but in the pages of a magazine. After graduating in London with a degree in journalism, publicity and promotion, Muller joined Miss Vogue as an assistant beauty and teen fashion editor — a position that sharpened her eye for image, narrative and the mechanics of desire that underpin the fashion industry.

It was a single photo shoot, however, that would redirect her entire career. Styling Guns N' Roses for Details magazine brought Muller to Los Angeles for what was meant to be a six-week assignment. She never left. The city, with its peculiar alchemy of celebrity and commerce, became her permanent home and her professional canvas.

The Bold, the Beautiful, and the Emmy

In 2001, Muller joined the CBS daytime drama The Bold and the Beautiful as in-house fashion designer — an internationally syndicated series whose entire premise is built on the world of high fashion. The appointment was a perfect match: Muller brought to the role not only technical expertise but a deep network of luxury relationships, featuring houses such as Chopard, Damiani, Harry Winston, Max Mara, Armani and Carlo Pignatelli on screen, transforming the show's wardrobe into something closer to a living fashion editorial.

The industry took notice. Nominated for Outstanding Costume Design in 2002 and 2003, Muller won the Daytime Emmy Award three consecutive years: 2004, 2005 and 2006. A fourth nomination followed in 2011. In the competitive world of American television costume design, this run of recognition remains exceptional.

Beyond the Screen: A Couture Empire

Television work, however, has never been Muller's only stage. Alongside her CBS commitments, she has built and maintained her own line of couture designer gowns — pieces that have graced the red carpets of the Academy Awards and appeared on the runways of the Dorchester Hotel in London. The latter was in 2010, when her designs were showcased at Eva Longoria's Humanitarian Noble Gift Gala, an event that supported both Eva's Heroes and the Make-A-Wish Foundation.

Her work extends to the sustainable fashion movement. For the 2012 Red Carpet Green Dress competition, she created a gown from organic chiffon with a recycled polyester lining — a piece that demonstrated that environmental consciousness and haute couture need not be mutually exclusive aspirations.

In 2009, Muller's reach extended beyond the fashion set: she designed gowns for Vanna White to wear during Wheel of Fortune's "Week in Las Vegas," cementing her status as a designer capable of crossing genres from soap opera glamour to mainstream American entertainment royalty.

Hollywood's Major Studios and Auteurs

Muller's career has taken her beyond the world of daytime television. She has worked across film and television productions for Paramount, Sony, Disney and Universal Studios, collaborating with some of American cinema's most significant directors: William Friedkin, David Lynch, Michael Bay, Francis Ford Coppola and Ridley Scott. The breadth of that list — spanning prestige art cinema, commercial blockbusters and genre filmmaking — speaks to a designer capable of adapting her sensibility to radically different visual worlds.

Her producing ambitions are equally wide-ranging. Muller is a producer on Pripyat, a film currently in development about the 1986 Chernobyl disaster in Ukraine — a Vero 8 Pictures production with a screenplay by director Alicia Hayes. She is also a brand ambassador and producer for Miss Liberty America, a reality competition that centres on knowledge of the U.S. Constitution and civic values.

Brand Ambassador and Industry Connector

Outside of design and production, Muller has built a parallel career as a brand strategist and connector. She is the founder of Brand Ambassador, a boutique public relations agency specialising in fashion, beauty, home and lifestyle sectors. She served as brand ambassador for British luxury furniture designer Christopher Guy Harrison, and has been a celebrity judge for the annual Christopher Guy Harrison BritWeek Design Award — a role that places her at the intersection of British and American design cultures, reflecting her own transatlantic formation.

She has also contributed fashion editorial expertise to top European publications including Vogue, Vanity Fair and Elle, and began her career in proximity to celebrity styling when she worked as a photo editor at Transpacific magazine — a period during which she styled a then-rising Angelina Jolie.
