Hi. I was looking to find whether Extra Chico would be the way to say Extra Small in terms of the size of clothing. I used the word tamaño to do a web search to see what I would get. Then I went to WR to look. It interested me to learn that talla should be using for size when speaking about clothing. And yet, there were lots of references to clothing with the word tamaño online. (Yes, I know there are errors on the Internet!) Are talla and tamaño used differently in some countries and are interchangeable in others? (I know that these words have been discussed on WR but not in this manner.) Thank you.
