Hi Bill.
Glad to see another Brit on here.
BHS! I think the first shop I ever saw a men’s thong for sale was, believe it or not, C&A! Another former bastion of the UK high street. Our old branch of BHS was very poor for menswear, which had so little space devoted to it. Other towns though were much better.
Debenhams was still pretty good for stocking their own brand last year. When I first started buying thongs they stocked YSL ones, which were similar to the CK Body ones but cheaper (and just as good quality).
Selfridges in London used to have a fantastic selection.
