In case you haven’t noticed, people come in all shapes and sizes, but one thing for sure is specialty sizes can be a nice niche to market for your resale store. Finding multiple choices in stylish colors and designs in either very petite or big and tall sizes can be hard to find. Be on the lookout for shoes or jackets and social, party wear items. Be sure to check seams and look for any flaws or imperfections that you should skip over. Make good choices to reduce the odds of returns.
Check estate and garage sales to try and locate someone selling multiple items in specialty sizes to get better deals.
I remember my father needed a size 14 shoe to be comfortable but growing up in a small town and a limited budget really made it difficult to find his size and I remember more than once seeing him squeeze his longer feet into a size too small because his options were limited.
Yes there are many companies on the internet now that can provide specialty sizes, but most of these come with specialty prices. As a specialty seller of preowned clothing in well kept condition, you will be providing a service and savings to a broader market. Offer your clients a chance to save and expand their own closet at affordable prices where you both reap the benefits. And if you are able to focus your sourcing on multiple items of specialty sizes, you may even be able to bring in repeat clients and bundle purchases.
Good luck and happy hunting!
