I was thinking of adding some Sephora to my cosmetic bag. Can you tell me about it?
Sephora features 300 brands long with it's own private label, so you would have to be careful in your product selection to purchase only sephora products. 
Wow that is a lot of products. I think I just need some mascara and blush.
They seem to be a relatively young company. The French chain was founded in 1969, but the first store in the United States was opened in1998.
Oh so they have their own stores. I will need to find out if there is one near me.
Just look for the Sephora logo which is a white "S" shaped flame on a black background. 
I definitely will. I think the French have good fashion sense so I will look great.
They have a "assisted self-service" customer experience, that encourages customers to try products in-store before purchase. 
What a great concept. I would rather try different products before settling on one.
