Trained at Central Saint Martins, with internships at Giorgio Armani and Vogue in New York, Wickstead built her house on craft: a £5,000 start, early features in Tatler and Vogue, a store in Belgravia, and a team of seamstresses. Her first London Fashion Week show came in 2012.
Her style has been described as 'graceful' and 'understated elegance,' her colours 'pretty but not saccharine.' Among those who have worn her designs are Catherine, Princess of Wales, Samantha Cameron and Melania Trump. In 2014 she won Red Carpet Designer of the Year at the Elle Style Awards, and in 2023 Air New Zealand named her its future uniform designer.
