It's an MTM operation. Shirts and Suits are manufactured in China.
I ordered a white dress shirt with french cuffs about 5 weeks ago. I went in for a fitting yesterday. There were a few problems with the shirt. Chest, waist, and sleeves were a good 2" roomier. Shoulder was also wider by about 1/4".
The guy who measured me, Rafi, said the factory probably adjusted the measurements because of the size of my chest (41"). For reference, a brooks brothers 15.5/32 extra slim fit fits me well.
Anyway, Rafi decided that it will be too much of an alteration so he will have the shirt remade.
I would also like to add that a very tall and slim guy was just finishing his suit and shirt fitting. He seems to be very happy with his purchase. I got the impression that his suit and shirt went through some adjustment locally.
They have Loro Piana, VBC and Zegna fabrics in addition to their standard line.
