Update. I met with Andrew Toth, who has essentially taken over for Freddy V. (retired). Andrew trained with Freddy V. for one year and has the shirt patterns for Freddy's previous clients. He is located in West LA near Westwood Blvd. & W. Olympic Blvd.
Andrew has access to Albini, Grandi & Rubinelli, Thomas Mason and TESTA fabrics. He is open to CMT, but you will need to speak with him regarding pricing and shirt minimums. For an upcharge Andrew can also do handmade button holes.
I also examined the stock buttons Andrew utilizes and I must say they are pretty good quality. The MOP buttons are similar to the AK MOP buttons. Buttons are hand shanked.
I commissioned one shirt to get a feel for his work and to gauge if he will be a suitable replacement for Freddy V. I will grab some photos from my next meeting.
