Celebrity Lessons in Selling

Gwen Stefani There's nothing wrong with a little shameless self-promotion.

Since singer Gwen Stefani started her clothing line, L.A.M.B., eight years ago, it has grown to not only include apparel, but shoes, accessories, bags, watches, and fragrances. Stefani's own promotion of the line has been a key strategy to build hype. She wears items from L.A.M.B., especially during public appearances, and refers to it in songs such as Harajuku Girls, singing, "Just wait 'til you get your little hands on L.A.M.B." Don't shy from talking up your products at every chance, and if your products are portable, flaunt how unique they are.
