I never actually owned one myself per se,but I bought one for a girl
friend of mine who liked to ride.I paid £15-00 for a size 18 riding mac
in a second hand clothes shop.It was off-white,full length and full skirted
and my girl friend filled it out perfectly.She could get a bit bossy in it when
she was buckled and buttoned into it with the leg-straps done up and with a
crop in her hand.
The rubbery aroma was heavenly ,especially when she had been wearing it
for a while and it had warmed through.She always wore it for riding and she
said she liked it very much.The other girls at the stables were a bit jealous
because it was such a nice mac.This was in the early 80's and these macs
were starting to go out of fashion.
I found this riding mac a real turn on when she was wearing it and it
even made it into the bedroom a few times.All in all it was a wonderful
garment and I was sad to see it (and her) go when we parted. She kept
it and I believe she still has it but she is married and lives in a different
part of the country.
