Hi, i've been asked to spray a bride & 2 bridesmaids for the wedding on Tuesday. They haven't had a tan before & i don't think there's enough time to do a trial, although there is for a patch test. I've explained this & agreed to tan them on Sunday. I've never done a bride before but everyone who i tan loves it. I use SiennaX 10% on pale skins & Nouvatan 10 or 12% on more olive types. Have you got any advice for me please? Should i go ahead? I've done girls who were going to proms wearing baby pink dresses 2 days before & their dresses were fine, but i'm concerned about white lace/silk - do i need to do anything in addition to avoid staining?
