Thanks Jonathan: I've done that one too. I can't even think of all the terrible things I used to do to vintage before I respected it as much as I do now, but I guess that's how we all learn.
During the '80s I had hundreds of cotton floral print dresses, most of which I rehemmed to a shorter length.
I shudder to remember a stunning WW2 skirt suit I had in red and black. It was a size 14 and I cut the whole thing down to fit my size 6 (US 2) frame. Despite my costuming skills, the jacket never did sit well and eventually I disposed of it. Now, I'd kill to have that suit but I didn't care about the size 14 ladies I was depriving, only that it was mine, that I loved it and it needed to fit.
I try to redeem myself through my daily restoration work and try to dissuade customers from making huge alterations to vintage garments, that would destroy the original design.
