It's true that they like to show off expensive winter clothes. Note men in Recoleta who wear very expensive overcoats when it hardly justifies a jacket. I have been dripping with perspiration from a brisk walk in humid winter while some men go around in suits and overcoats that would keep them warm in the coldest climates. Also I agree that Argentines (at least the older ones) react to any drop in temperature. They overheat their homes and use inadequate air conditioning in summer. I'm always uncomfortable in malls and restaurants in warm weather. Are they genetically different?
