Purple dresses are having a real moment and we’ve been fully converted. From deep plum to lavender to bright violet, every shade has a richness that photographs brilliantly and looks genuinely distinctive in person. It’s a colour that works across seasons too, lighter purples for summer, deeper plums for autumn and winter. We’ve been pulling together our favourite purple dresses across styles and lengths. The ones that prove purple is not a supporting colour but an absolute leading one.
