After a blind date, I want to ask another girl out. How can I send a text message?

You must find a suitable reason to ask a girl out. Don't ask people directly when they can come out next time. A reserved girl is embarrassed to say yes if she wants to.

You can say: the company has important activities and needs to choose a dress. But I don't know what to do. Ask her if she can help me choose. Because girls have better eyes than boys. That's much better.

Similar reasons can be handled flexibly according to your own situation. Good luck!
