Many young women like fast fashion fan Hollie are very familiar with how easy it is to buy a brand-new outfit for a special occasion and then not wear it again. In 2014, the then 18-year-old decided to clear out her wardrobe and sell old outfits on Depop to make some extra cash.
If you're not familiar with Depop, the app lets people buy and sell unwanted outfits and has started a revolution in the second-hand clothing market - and has help savvy seller make thousands.
Hollie started casually using the app while living just across the Bristol Channel in Cardiff after getting "super bored" of the clothing she had - but she now nets a sex-figure salary after becoming a top seller.
