Getting feedback from others is also good, your friends are more objective about the way you look then you are. Another pet peeve of mine, Imagine going through a practice run and loving what someone does for you. This happens and it can be very freighting for the bride. Make sure that this make-up artist has never done this to anyone and never will. You of course want the full version, go ahead and pay for the full version if the artist offers only a partial for free, this will not be sufficient.
Experience is something very hard to fake.
You may want a make-up artist that can come out and do both. I will repeat, to find one person that you like for both will be a real trick so keep your options open. I think it s a good idea to look at the artist s portfolio to get an idea of their style and what beauty is to them. You should know after your practice run. If you have any doubts about the artist then call a few references but do not let this be a substitute for a practice run.
