Can I come here in scrubs ? or is there a dresscode ?

I would say no scrubs

A work to dinner attire would be accepting. However, scrubs would be appropriate if you came to attend to the injured.

I agree with Gwendolyn, most likely they will not say anything. That said, you will feel uncomfortable as everyone else will be "dresses to go out."

I think scrubs might be frowned upon. However, they may not say anything.
