You have heard the saying blondes have more fun, however, brunettes seem to have more selling power.

A lingerie and bathing suit company, Adore Me, put this theory to the test in an ad campaign to see if different ads resonated differently with consumers.

The commercials, one with blonde models, one with a plus-size brunette model and one with a variety of brunette models were run on Bravo, Lifetime and MTV.

The commercial featuring the a plus-size brunette model quadrupled online sales when compared to the blonde commercials.

The boost didn't just come from plus-size sales, it also helped break the mentality that you have to be super skinny to buy lingerie.

What Do You Think? Does hair color and size matter when it comes to your decision to purchase a lingerie products?
