She is coming to the USA this year with the tailor to the King of Spain.
I had her make me some shirts when I visited Madrid. Her shirts are very nice, without anything distinctive like noticeable handwork. Her prices are extremely reasonable, especially if one selects fabrics manufactured in Spain. She carries the full Alumo range, which is something American shirt makers do not. If Vandecasteele is "bottom tier" in price and Charvet/Kabbaz are "upper tier" in price, I would say she is right in the middle. I will let her state prices but as we all know there are complexities and I don't remember how much my shirts cost, each was a special case. One distinctive thing I can say about her is that Burgos appears to have special expertise in formal dress, so they are a very good place to get shirts for your tuxedo.
I did not try the tailor she is traveling with though I visited his atelier (it looks like an atelier, with workroom visible from the elegant fitting rooms). I think I will try him if he comes to the USA, I would love to see the Spanish style in suits, and there are some fascinating pictures on Cutter and Tailor.
Before you ask me "how my shirts fit", she did not really have a chance to do her best with my shirts because I had one fitting and never returned. But they fit fine and I enjoy wearing them. I have no business interest in Burgos, I am just posting this to be nice. Though Carmen did tell me I could get 100 free shirts if I help her.
