I'm by no means a sewing expert, but here's what else I can tell about this jacket.
(1) It is very well made - perhaps even better than my new Chanel jackets.
(2) Like newer jackets, it is made of of several 'parts' or 'panels' and corresponding silk lining panels, presumably to allow for easier tailoring.
(3) The buttons are unmarked, and there is no chain on the hem, however. I have new Chanel cardigans with no chains on the hem, though, so I thought maybe some of the older ones also don't have these chains.Is this true?
Thanks for any input you may have - I really appreciate it. I'm new to vintage clothing, but so far, I am loving it! The pieces I have started collecting have been very well made and very unique.
