If I may dolly mixtures vinatge, in leicester:
http://www.dollymixvintage.com/# Sadly, they don't seem to retail through the website last time I was there they had stacks of enginers trousers, black wool trousers with braid down the sides, 4 pocketed wool waistcoats and scads of all manner of over coat.
The time before they had a ladies edwardian walking suit, and black beaded victorian capelet
They also have a pair of beautiful victorian ladies boots I keep going to drool at (as there asking price is ridiculous, i think they'll be there for drooling purposes for a long time yet)
The prices are a little variable, but mostly decent vintage prices/expensive second hand clothing price.
If you are there, then nip into goldrush in the malcom arcade, less of intrest but about a third of the price
