New research suggests that women's spending habits may be influenced by their menstrual cycle, with a particular inclination towards luxury goods around the time of ovulation. The study, conducted by researchers from South Korea and the United States, posits that elevated estrogen levels and increased fertility during this phase may drive women to seek more conspicuous consumption to enhance their attractiveness to potential mates.
The research involved several experiments. In one, participants were asked to draw logos of luxury brands. Those near ovulation tended to draw larger logos, which the authors interpret as a desire for greater visibility. Another study asked women about their purchasing intentions, finding that ovulating women expressed a greater desire to buy luxury products in public settings, but not in private. This suggests the behavior is linked to public display rather than a general increase in preference for expensive items.
A third experiment revealed that women near ovulation were more likely to choose a gift certificate to a luxury brand over one from a non-luxury brand. However, this preference diminished when participants were informed that men do not typically notice women's designer clothing, indicating a social-strategic element to the desire for luxury goods.
“What we found most interesting is that the effect of ovulation on luxury desire is not simply a general increase in preference for expensive products,” the authors stated. “Rather, it appears to be socially strategic: the effect becomes stronger when luxury consumption is visible and personally relevant but disappears when women believe that men do not pay attention to such signals.”
The luxury goods market is substantial, valued at $484 billion this year, with women accounting for 56% of purchases in fashion, beauty, and accessories. While it is often theorized that men purchase luxury items to signal their mate value, this research suggests women's luxury consumption may also serve a signaling purpose, potentially to attract mates or to signal high standards to deter undesirable suitors. Another theory proposes that women may buy luxury goods to demonstrate their partner's resources to other women, serving as a form of self-promotion.
