While enjoying a wonderful paella in Madrid I overheard a Madrileña that was close to my size speaking of fashions and the difficulty in finding something nice for large women. I rudely interrupted
and asked her where she went to buy clothes, because she looked exceptionally elegant ( she did too
)and she told me that most women our size use the services of a costurera (seamstress). Hers was retiring so she was real miffed about that. So perhaps the same is true for men, except they would go to a sastre(tailor)?
