Look at those legs

Question

How do I say "look at those legs?"

Do I say "mira esas piernas" or "mire esas piernas"

Answer 1

It depends on whether you are adressing the person informally ( mira tú) or formally (mire usted)

Answer 2

Miras esas piernas if you are saying this to a friend or workmate etc. Yo miro. Tu miras. El or usted mira, mire is the subjunctive 1st and 3rd person form but in the context of your speech you might use the imperative !Mira¡ which is 2nd person.
