I know I'm way too old for that shop normally but was in there today and they've got a beautiful dress in the sale. It's a 50's prom dress in a soft beige silk with a pink print on it, also has a net petticoat under it and a wide sash, nipped in waist and no sleeves. It's really pretty and is 25 quid - down from 60. Will try to find a link.
They had some other bargains too - top sale
