Just been into an H&M store (Norwich) and they had some lovely prom-type dresses in bright pink or stone colour for £7! They are short with a strapless, ruched top and a flared, knee-length skirt. I thought they were lovely and would have bought one for myself if only I were 20 years younger and 20lbs lighter!
Just a thought for anyone dreading the thought of having to spend lots of £ on the horrible American import prom.
