I strongly believe that he did the right thing by her flashing skin for sales. If you want to achieve the best results in your sales business, then you just have to do what it takes. We should not judge her simply because every entrepreneur does the best to boost their sales no matter what the critics will say.
Yes, Kylie has every right to promote her business as long as she keeps in within legal bounds. There has always been a history of showing skin to boast sales and as long as she is not dressing nude in the streets she is entitled to market her business as she pleases.
People like to look at beautiful people, and many consider Kylie Jenner to be attractive. She and other members of her family have demonstrated many times that they are willing to do just about anything for money. She uses the attention garnered from controversial advertising to increase sales of her cosmetics.
Yes, Kylie Cosmetics is flashing skin for sales because they understand that sex sells. People are more willing to buy something when they pay attention to the advertisements. By showing a little skin, people pay attention and will consider buying the product later. It should not be this way, but it is.
