I think it's not just about the bride. It's far too bridal, and even if the bride is fine about it, you might risk offending the mother of the bride or groom, the wedding party and other guests will be commenting.
I went to a wedding where one of the guests wore a cream evening dress. Apparently she'd checked with the bride, and knew the bride wasn't going to wear cream, but even so, all the other guests were commenting. When the groom showed wedding photos to colleagues who weren't at the wedding, and they all joked about her asking if she was hopeful he'd marry her instead...
don't be that person. It's far too bridal.
