Spay tan !

I have SiennaX spray tans, no transfer or smell and as it works with your natural pigments it doesn't look fake at all. I would panic if I saw transfer as you did, but maybe speak to your tanist and see if you need to do it a day earlier than planned so you can wash off and then shower again before the big day

I also have siennaX spray tans and it never transfers! I would get another trial one done somewhere else and get your actual spray done a couple of days before the wedding.
