Shopping for Clothes — Asking for Your Size

You see a shirt or dress you like and need to ask for the right size.

You
Disculpe, ¿tiene esta camisa en talla mediana?
dees-KOOL-peh, TYEH-neh EHS-tah kah-MEE-sah en TAH-yah meh-DYAH-nah?
Excuse me, do you have this shirt in a medium?
Latin American clothing sizes often use S, M, L like the US, but asking in Spanish shows respect.

Let me check. No, we only have large and small.

Mmm, me llevo la grande. ¿Tiene en otro color?
