Born in Norway, Dundas studied at Parsons in New York. It was there that his obsession with the female body began; an obsession he would take through his design roles, with an eye for complementing the female figure with his talent for cut and pattern.
In 1992, Dundas became design assistant to Jean Paul Gaultier , where he stayed for eight years. All the while building up his experience, in 2000 Dundas moved to Lacroix, where he developed a sense for striking colours and patterns. After a stint as creative director at Emanuel Ungaro, Dundas was appointed artistic director at Emilio Pucci, owned by LVMH, in 2008, before returning to Cavalli.
During his seven-year tenure at Pucci, Dundas developed the brand’s history of glamorous, colourful and patterned collections. Focusing on nightlife as a key inspiration, Dundas took Pucci in a new, youthful direction. It was under the creative helm of Dundas that LVMH identified the label as a key future-growth vehicle, branching into new product categories such as shoes, handbags and eyewear.
In 2017, Dundas started his own namesake label with co-founder Evangelo Bousis. The looks launched exclusively with Moda Operandi in July, and were followed by a partnership with Farfetch in autumn. The label is conceived around a non-seasonal structure, released in drops to coincide with the demands of clientele.
In March 2019, Art of Elysium named Dundas the recipient of its Visionary Award for 2020, with the designer creating the decorations for its annual gala on the theme of "Heaven." The brand's D7 collection also premiered at Art of Elysium's event the year prior.
