Yeah, since I'm going to be in Paris in August, I emailed Charvet but haven't heard back. Have also been in contact with some other Parisian shirtmakers, but I had forgotten that the city is shut down for the month.
However, I think I'm going to have to put a pretty heavy weight to having tailors located in my immediate vicinity, at least for shirts. I can probably manage working with traveling tailors for pants, jackets, suits, etc., especially if they visit every 2 months a la Rubinacci.
Any experience with high end bespoke items? Just making sure your expectations are reasonable.
