we bought our daughrers wedding dress...now she wants to take it home so she can try it in she;ll we let her?

our daughter annouced her enagement 2 weeks ago, 2 days she called to say she found her dress..without anyone going with her, she wanted us to pay for it and pick it up...she also wants to take it to her house..so she can try it on and "play" with it...i disagree, what do you think..Am I being too old fashioned the wedding is more then a year away????
