After seeing sexy women guys are more interested in products that increase their status:
In two experiments we demonstrate that men display an enhanced interest in status enhancing consumption upon exposure to mating cues. Men indicate a higher interest in high-status products (study 1) and more readily noticed high-status products (study 2) after exposure to sexily, rather than plainly, dressed women. The effects are restricted to single men, suggesting that the acquisition or consumption of a luxurious product functions as a mate attraction mechanism.
