I washed a top that wasn't suppose to be wash and now it looks weird, how do i fix it?

The top is 100% viscose, I have washed this type of fabric before without it looking weird after. This top after I washed it looks like it shrunk and the fabric looks likes it is stretchy (dont know how to explain) I tried to iron it but it doesn't work. Do you think if I bring it to dry cleaners it would work??
