Does anyone know where the dress that Rosie wore in tonight's episode is from?

i know!!! i really dont want her to die!! and the music they played and the way the looked made it seem as if she died!! but she is coming out of wild at heart. but without her the kids will have to go back to their dad unless they think of some wonderful way around that.. so if shes gone the kids are gone and rosie is going to go to university. ...

Does anyone think that max and rosie will actually get married? I ave seen clips where he leaves the party because she has not told danny and sarah that they are engaged. After this incident does anyone think that they will still go through with it and when?
