Como dizer "Estou procurando algo para menina" em inglês

Eu posso dizer "I'm looking something for girls"?

I am looking for girl´s stuff.

But you could also specify "I am looking for clothes for girls/toys for girls" etc. When you refer to babies, you could use some sentence like this: "I am in the hunt for some clothes for my little man/little girl."

She is mainly looking for girls stuff, you know, t shirts, tops, kurtas, bags, sandles etc. Not super expensive, but decent brands or local street shops...

Let´s wait for further comments.

Thank you a lot! You answered my question.

Glad that it somehow helped.
