Why do you suppose Victoria's Secret commercials, models are in heels most of the time and the other bra maker commercials they are not?

Nothing big just something that makes you go ummmmmm. Ever noticed those Victoria’s Secret bra and panty commercials? Ever noticed whenever you see the model’s feet she is in heels? When you see bra commercials from Playtex or others their models are never in heels, ever noticed that? Why do you believe Victoria’s Secrets seem to always put their models in high heels to peddle lingerie when the others manutacturers don’t do that? Make you go “ummm…..??”
