Hi! I think very highly of Turnbull and Asser. I wore t&a shirts exclusively for more than 15 years. The quality is outstanding and I still will wear most of the shirts that fit( a few have shrunk). I have worn both bespoke, MTM, and rtw and the quality is consistently high. I changed Shirtmakers about a year ago because of a couple of bad bespoke orders. I also went to bespoke because they changed. Th cut of the shirt to be slimmer fitting. While they fit fine, I really loved the old style. I think you will really like their shirts.
Thanks for the reply Sounds like I will be happy with a few of these shirts It will be interesting to try a real high-end product, compared to what I have now
