Thousands of men sell women's clothes, shoes, handbags, jewelry, accessories, and cosmetics everyday in some of the best stores in the world. What's wrong with a male salesperson doing the same on TV?
If I may add my favorite Lancome salesperson in the Chicago area is a man. He's so good at his job I often go out of my way to get to his counter to make a Lancome purchase-- and definitely to explore new products.
