On Market street in Manchester it'd probably be Lewises.
Kendal Milnes did most of the "better" schools. Became House of Frazer, and currently, sadly, in the throes of closing down sales, after all these years.
I seem to recall Pauldens, and Affleck & Browns, on Oldham Street / Road may also have been accredited suppliers, and probably Debenhams on Market Street may have been, too.
