There used to be a bra shop in Reading. I would go there and ask for a referral.http://www.google.com/search?q=bra+shop+��
I don t know of any shops or stores that do this kind of custom work; you d probably need to work with an individual tailor or seamstress. It won t be cheap, however. I know someone who might be available for custom work if you want to contact me. There are lots of places to buy corsetry online, so if it is for wearing under clothing you can probably find something cheaper (though not custom) online.
