In the early 1990s, Sindy celebrated her 30th birthday. For the occasion, the PR manager for Hasbro (who at the time had the licence for Sindy from 1986-1997) organised a party.
Sindy wore an outfit designed by British fashion designer Vivienne Westwood – a sateen dress with corseted bodice and padded skirt, a crown-style hat over elaborately styled hair, and pink ballet wedge heels.
The party was held on a glass-roofed venue in London and was attended by Vivienne Westwood and her muse, model Sarah Stockbridge, who wore a real-life version of the costume. They made a small outfit for Sindy, but it never went into production and only two were made. One, with a shoe missing, was sold at Vectis (A Specialist Toy Auctioneer) where it fetched £260 (around €311/$ 338) in 2017.
The other is in the V & A Museum of Childhood in London who have a great collection of Sindy’s on display.
