The answer in every case is no. Don't be ready when we go to your room.
We'll need to photograph details, jewelry, your wedding dress and everything else you might have before you wear it. Even if you didn't want pictures of your accessories, we'll take pictures as you put them on.
For the Groom & Groomsmen: He can shave and shower before we get there, but that's about it. No wedding attire before we get there.
For the Bride & Bridesmaids: Hair & Makeup before is good, but nothing else. If you are wearing matching robes with your girls, wear those for the getting ready.
