I am planning on changing into a going away dress before leaving the reception. I've seen other posts about pros and cons of a going away dress, and since we're embarking straight on our honeymoon with a 5 hour drive I decided that was best for me. I haven't seen much about the practical how/when of changing though. We're having a simple luncheon reception, no dancing or anything. Do I sneak out with a BM or someone to help get me out of the dress while people finish up the cake and then just reappear? Thoughts/strategies? I don't think it's that big of a deal but wanted to make sure there's no etiquette for this I am unaware of.
