Gen MZ’s Spending Habits ; Between Conscious Consumption and the ‘Flex’ Culture

Flaction & Namuwiki

Generation MZ, which includes Millennials and Gen Z, is changing the landscape of consumer behavior. Their spending patterns reflect two seemingly opposite values: conscious consumption and the desire to “flex” through luxury purchases. How do these two coexist in today's market?

On one hand, many MZ consumers care deeply about sustainability, environmental impact, and smart spending. This has led to a significant boom in secondhand trading platforms in South Korea, such as Danggeun Market, Joonggonara, and Bungaejangter. Buying and selling used goods is no longer seen as a sign of financial struggle, but rather as a smart and even trendy choice.

At the same time, “flexing” remains a strong part of youth culture. Many young people share luxury brand purchases on social media, using them as tools for self-expression and personal branding. Items from brands like Louis Vuitton or Balenciaga are not just products—they're statements.

Interestingly, these two trends have started to merge. A growing number of MZ consumers are now buying secondhand luxury items. This allows them to enjoy high-end fashion at a lower price while also staying true to their values of sustainability and smart consumption. This blend of “value and style” is defining a new type of consumer behavior.

In conclusion, Generation MZ is not simply being thrifty or extravagant—they are being intentional. Their ability to balance personal style with practical values is reshaping the secondhand economy and redefining what it means to consume in the 21st century.
