Theresa Blake trained at Wimbledon School of Art in period costume cutting and construction for film, television and the West End stage (ballet and opera). By combining this early training with her later experience in several major bridal houses, "Alternative" couture bridalwear design was inevitable. Today the resulting bespoke quality wedding gowns, corsets and ballet costumes are of an extremely high standard, perfect finish, and fit like a glove. Enchanting, often coloured, couture wedding dresses and bridal corsets, inspired by Pre-Raphaelite art, Medieval and eighteenth-century historical fashion, can be commissioned from a designer who also produces totally unique one-off contemporary designs.
 
Theresa divides her time between designing/ making bespoke wedding gowns for the Rossetti label, and constructing costume for prestigious ballet companies and award-winning competition ballet dancers. More recently, owing to frequent requests, she has started to provide individually tutored one-to-one classes in tutu construction: cutting, making and embellishment.
 
Credits include tutu-making and costume-making for the Royal Ballet's principal ballerinas; The Royal Shakespeare Company; for film and television costumiers and for Cameron Mackintosh. Theresa has made headdresses, jewellery and tutus for major ballet companies including English National, Scottish and Moscow Classical Ballet. She has worked with top couture bridal designers including Basia Zarzycka and Ritva Westenius. The potential of positions with Vivienne Westwood and Elizabeth Emmanuel in the late 1990's inspired her to establish the Rossetti label and follow her own design inspirations in bridalwear, while maintaining her connections with the theatre.
