I think Ray went to Sam's didn't he?
I pick up Jantzen's first attempt at a copy of a British 1920s shirt tomorrow. Very sharply pointed collar, British half-buttoning style, very wide in the body. made in Liverpool prob late 1920s.
The looks I got when I told them to "copy it exactly". They tried to talk me out of it for about 15 minutes before they gave up. Very important was telling them that of course I would pay more for the extra fabric used. Their standard shirt price is HK$380. The 1920s shirt with the extra work involved and extra fabric is HK$80 more expensive. Still a steal at the price (if it's any good).
I'm hopeful. I urged the chap to keep the pattern, if they're any good at it, and offer it on their website. Watch this space to see if they're any good at copying shirts (I of course take no responsibility for anyone else's future disasters with this company/pattern) … I picked a fabric very similar to several vintage shirts I already own, for that 1920s/30s look.
