Any more updates here fellas?
I'm tossing up whether to go with PJ or SS for a wedding suit...
I think that they use two manufacturers in Italy, one in Rome and one in Naples.
In Naples, they've been using Orazio Luciano, also known as La Vera Sartoria Napoletana.
I don't know who they use in Rome, but you could always ask them.
Perhaps there's some confusion here because P.Johnson now has two businesses.
There's P.Johnson, which used to have its suits made in the Netherlands but which now largely has its suits made in two different places in Italy.
Then there's Suit Shop, which was the original name of P.Johnson Tailors before Patrick Johnson decided to call it P.Johnson Tailors, and which has now been brought back as a "budget" line.
Suit Shop suits are made in China, although I don't know whether they are made by the same place that makes suits for Suit Supply.
TL/DR version: P.Johnson suits are made in Europe whereas suits from Suit Shop, the cheaper subsidiary of P.Johnson, are made in China.
