Hi all, Congrats to every one of you! I ran into a family friend and old neighbor the other day who offered to do my make-up for free the day of my wedding! She would charge my bridal party of 9 but offer a discount too. I was already thinking of asking her anyways because she's done my prom makeup in the past when I was younger and I loved it! This is a steal but how would I go about tipping her? I want to thank her and since she's already giving me free make-up obviously I'd be happy to give her a big tip but what is acceptable? Should I base the tip off of what the girls will be paying? Best, KC
