What does “polera” mean in Spanish?

In this sibling argument, one kid asks “¿Por qué te ponen mi polera?” — roughly “why are you wearing my T-shirt?” In Spain you’d more likely hear “camiseta,” but in Chile, Peru, Bolivia and Argentina people say “polera” for a plain T-shirt or casual top. If you hear it in a home scene, it just means someone’s basic shirt.

In the clip: “¿Por qué te ponen mi polera?” — “Why are you wearing my T-shirt?” More examples: - “Me compré una polera nueva.” — “I bought a new T-shirt.” - “Esa polera te queda bien.” — “That top looks good on you.” - “Ponte una polera, hace calor.” — “Put on a T-shirt, it’s hot.” Notes: “Polera” usually means a simple T-shirt or casual top in countries like Chile, Peru, Bolivia and Argentina. In Spain and many other places the common word is “camiseta.” The meaning can shift a little by country, so it often just means “casual shirt.”
