Noni B isn’t a bad little chain for finding things like formal dresses, mother of the bride outfits, etc. The Doncaster store in particular often has some decent sales. My mum picked up an outfit for my wedding from the Doncaster store, for over 50%. The staff at this store are great too, they spent ages helping us find something for mum, and it didn’t feel like they were pushing for a sale. Generally the prices are on the expensive side, but they are relatively priced to similar stores.
