Once again, I say, if you want to sell bikinis or underwear, don't be the dolt in marketing who needs to come up with the new idea. Check the project budget and figure out a way to hire Irina Shayk to model your silky little bits. There is simply no better way to create a must-buy sensation among your audience than by seeing the wicked hot Russian model preening and posing in your fineries. Naturally, I may only be speaking for the man folk who use fake names perhaps to purchase these undergarments, but by the sheer volume of her work, I'm guessing these companies are also finding tremendous sales upticks with Irina Shayk's supremely hot body leading their promotional charge.
Irina Shayk could see water to a drowning man, provided that water were carried in the cup of her recently removed bra. At that point, you just stop fighting and know that you're going to a far better place with the taste of Irina Shayk funbag in your mouth. Things could be worse. Enjoy.
