If you are interested in mineral makeup, even if you already use it and just want to restock your supply, it's worth a visit to one of their boutiques. This well-appointed little boutique near Neiman Marcus inside the Fashion Show Mall on the Las Vegas Strip is a quiet, calm, happy oasis. The very helpful staff quickly got me into a chair and tried a few different day and evening eye makeup looks (what I walked into the store for.) They also checked to make sure my daily routine is working, including confirming that the shades I use still fit my skin tone. I really appreciate that there was no attempt to sell me things I didn't need. Very low pressure, very friendly, very easy-going.
I learned some simple new techniques which I will incorporate into my daily makeup routine at home.
If you are a regular, get a punch-card, which entitles you to free products. One potential drawback for visitors to Las Vegas is the insanely high Strip sales tax -- 8.1%! But other than that, definitely worth a visit.
