I did the full session at Sephora, which went well over the 90 minute mark. Everyone was very helpful, and I got quite a few people to stop, and watch. I was a bit nervous at first, but it was a great experience in the end. Sadly I was so excited, I purchased way more than I planned. Final total was just over $400, and I could have easily spent more. I did end up with some great makeup, but I probably could have done with much less. One negative (besides the cost), there was way more than I can remember, and I have trouble with some of the steps. They were great in giving me drawings, but it's still a lot. My suggestion would be the shorter session, or take advantage of the 15 minute quick demos where they show you one thing, like eye shadow. Visit during off-hours, and you will get much more attention, since they are just waiting for their shift to be over.
