Resale sites and apps, such as Depop, Vinted and ThredUp, have been taking the world by storm over the past 12 months as consumers re-evaluate their wardrobes and consumption habits. 

Depop is the 10th most-visited shopping site for Gen-Z consumers in the US, with more than 90% of its buyers and sellers under the age of 26.

Etsy, meanwhile, has carved out a niche connecting independent creatives and small business owners with shoppers seeking unique and vintage items. The business also has a much broader age demographic than Depop, with an average seller age of 39.
