1909: Mappin & Webb advertised “suffragette jewellery” in purple, white and green: brooches and pendants set with amethysts, pearls and emeralds. Shoemakers Lilley & Skinner introduced “bedroom slippers in velvet and quilted satin specially dyed in the colours”. And a certain Miss Smith, of Barnham, in Sussex, also specialised in the purple, white and green of the suffragettes – in her case, sweet pea seeds sold by mail order.
