I got answers to a lot of these yeterday but still have a few I@m unsure of.
All answers are well known shops past or present (some as spoken ie with s added to end
1 Choristers (7)
Could it be Singers ?
.2 Stunning tails (8)
There was a well known local shop called Dressers but I am dubious
3 These are needed in Civic Theatre (8)
Curtains but have never heard of shop by that name
