My RN uniform was a Bernards special which I was reliably informed at Dartmouth was not really an orfficers' tailor. When I joined the Air Force, my nearest tailor was G & H in Camberley. When I went in there to get my uniform made, the conversation went along the lines of:
"Good Morning sir, how may ai help you?"
"I would like to be measured for a uniform please"
"Certainly sir. May ai enquire which Regiment or Corps?"
"The Royal Air Force"
"Oh I see. Nigel - do we do the the Royal Air Force?"
"Yes, I think we do. I will check"
Muffled muttering and shuffling of paper
"Yes Rodney, it seems we do"
"Jolly Good. Would sir care to step this way"
The final result was not bad but the fit was not as good as the Bernards Special.
Subsequently, when was I on the DS at Bracknell in 1999, I did pop in for another best hat as I could park in Sandhurst and wander into Camberley. Unfortunately, the G&S website does not list a shop in Camberley any more.
