Thanks to a LondonLounge thread by Guille, I recently discovered that I had misspelled the Teba jacket in my previous posts on the jacket and Barcelona. These misspellings have been fixed. Apparently the jacket is quite popular in Madrid. Guille also provides a photo of Madrid-style Teba jacket, which looks a bit different from the one Bel y Cia made for me.
He has also helpfully compiled a list of five tailors and one shirtmaker (Burgos) in Madrid.
