if you want the best, Bobamaker, LadySewForUs, Loanstar, just to name a few...they can take care of you...being in the UK, Loanstar and Bobamaker would be closer...LSFU is in the States...hope that helps...
I bought mine from a seller on ebay, cucblack or something... He is from Bolivia and makes killer suits by hand. You have to send him your measurements though, about 15 I think. I have been impressed with the quality so far. I have actually ordered several items from this seller and have incorporated them into my work...in...progress... Maybe someday it will be finished
