Maier's early professional experience includes designing for several fashion and luxury goods houses in France, Italy, and Germany, including Guy Laroche, Sonia Rykiel, where he designed men's wear for eight years, and Revillon, where he spent four years as creative director. For nine years, Maier was a women's ready-to-wear designer at Hermès, where he also designed some leather goods and accessories. By 1999, he quit all his contracts and moved to Florida.
Bottega Veneta, 2001–2018
Maier was appointed by Tom Ford to become the Creative Director at Bottega Veneta in June 2001, when the company was acquired by Kering, formerly Gucci Group. During his time at Bottega Veneta, Maier presided over an extensive but deliberate expansion of the brand. He presented his first collection, which consisted solely of accessories, in September 2001, just a few months after being hired. In the first two years, he oversaw the opening of Bottega Veneta flagship stores in London, Paris, Milan, and New York, and added a small selection of women's and men's ready-to-wear pieces to the seasonal presentations. Among the product categories that Bottega Veneta now offers, in addition to women's and men's ready-to-wear collections, are accessories, fine jewelry, furniture, seating, tabletop, desktop, luggage, porcelain, eyewear, fragrance and watches. Maier helped found an artisan school, La Scuola della Pelleteria, in Vicenza in 2006. In addition, St. Regis Hotels in Rome, Florence and Park Hyatt Hotel in Chicago offer Bottega Veneta suites. In 2014, Maier and Bottega Veneta partnered with the Japanese publication Casa BRUTUS and launched an initiative to raise awareness of the potential destruction of numerous significant Modernist buildings in Japan due to economics, politics and the preparation for the 2020 Summer Olympics. Under Maier's leadership, Bottega Veneta tripled its revenues and exceeded $1 billion in revenues for the first time in 2012 before revenues fluctuated for the following years. By 2017, Saint Laurent overtook Bottega Veneta as Kering's second-biggest source of revenue; Kering announced Maier's resignation on 13 June 2018.
''Tomas Maier''
Tomas Maier established his eponymous swimwear label in 1997, with business partner Andrew Preston, and an online boutique was launched in 1998. Since then, five eponymous stores have opened in Palm Beach, Bal Harbour, East Hampton, and NYC. The collection is sold at over 100 stores in more than 30 countries around the world. On 19 November 2013, Kering announced it is investing in Tomas Maier's own label to "infusing it with the capital needed to ramp up expansion, including the addition of more company-owned boutiques"., the private label generated about $10 million in revenue annually from swimwear, knitwear, and jersey. In 2018, Tomas Maier teamed up with Japanese casual wear retailer Uniqlo for a one-time-only resort-focused collection.
