Are dressing rooms in the stores open

Yes, they are open.

There was only 1 store that we went that didn't have dressing rooms open. Think it was called The Loft

Yes, they are open. We used them in multiple stores.

We didn't need to use them but I'm sure they are. People were trying shoes on and things like that.

Yes

We didn't try on clothes, sorry I don't know.

When I went I think they were open but I didn't buy any clothes while I was there..

Depends how liberal they are
