A preview is different, now granted I haven't been to one yet, but from what everyone says it's not the same. The one I'm going to is on Aug.22 so that's a good week or so before the actual collection (Untamed) is launched and it's kinda where they showcase the new stuff and you get to buy it ahead of time. I think there's like drinks and munchies. I don't think they do your makeup there, more of a "meet and greet" for the new collection. If anyone knows otherwise, feel free to correct me.............
