Rehearsal dinner outfit

How many of you are planning to put together an outfit for your rehearsal dinner? Im just doing some online window shopping and saw some cute white dresses which I would have no where to wear because I dont wear dresses much but thought about maybe for rehearsal. But at the same time im not sure if its practical. The rehearsal dinner happens right after the rehearsal right?


I dont want anything over the top, I was looking at simple dresses/outfits. The only thing is that theres a lot of things going on the friday (day before the wedding). The day before I will be spending the whole day setting up the reception hall & then right before the rehearsal (1hr before) I will set up decorations in the church. I will most likely be in sweats all day to set up. We get the keys at 9am for the reception hall and access to the church around 5pm. Im hoping the reception set up wont take all day but maybe I wont have a lot of time to change my clothes and get ready in between. And our rehearsal dinner is going to be pretty casual we probably will go to a place like Buffalo Wild wings or we will be ordering pizzas at home.
We plan to elope in June. Should we even still have a rehearsal dinner? And if we do, to dress up or not? Another sub question: for those that diy decorated for your wedding how long did it take to set up.
