The first thing that you should consider when trying to rebrand is identify your market's most common objections.
Why are consumers hesitant to purchase second hand clothing?
Once you've identified these problem factors, you can start developing a strong marketing strategy.
For example, second hand clothing often triggers thoughts of "old", "worn out", or even "out of style." None of these are very appealing, and will force consumers to look the other way. Consider how you can effectively combat these thoughts.
A possible solution may be how you're marketing your products. If you're selling products piece by piece, you could try marketing entire outfits.
By showcasing the second hand pieces as an entire outfit, you can show consumers that the items are very much in style. As someone who has always struggled with being stylish, buying second hand clothes can be very intimidating. This is especially true for people who don't feel they have the fashion sense to accurately pair unique items and create a great outfit. By selling the pieces as entire outfits, you take the guesswork out of the styling process and make it easy for these people to buy.
I hope this begins to spark some creative ideas for you as you rebrand your marketplace.
