I don't know where you can get MTM Lorenzini in SF, but I do know Bloomingdales in SF carries Lorenzini RTW at $325 a shirt. The store carries the basic ones: white, blue, pink etc. The fabirc content is 75% cotton and 25% synthetic fabric. I wouldn't buy these shirts at that price. However, wait unitl December 1st, if you buy 5 shirts, you will get 30% off plus another $100 off. That will translate to $207 a shirt, assuming you are getting all Lorenzini shirts.
Lorenzini was named the best machine made shirt by Robb Report, at least twice in the past. I still think Fray makes better shirts - machine ones, that is.
That is rather disappointing that Lorenzini, a quality RTW shirt, would add synthetics in their shirts.
I know that the Nordstrom in downtown SF carries Lorenzini RTW, and they usually tend to carry patterns.
