Help please.

Good morning everyone,
I am planning a trip back to the U.K. in November/December time. I would like to use at least some of the time buying (and selling) costume & vintage jewelry. Can anyone recommend shops or malls that would be worth-while visiting? I will be in London for a couple of days, then mostly around the Bath & Bristol area.
Hopefully, I will get to meet up with you Lorraine?
Any thoughts or suggestions would be welcome.
thank you all in advance, Sue
