If you still want to buy imitations, go to COSPLAY store and sell them!
It seems that there is a COSPALY store in Xujiahui, or there are many booths for COS clothing during the exhibition! I've seen it!
There is also a COS clothing store on Qibaonong South Road in Minhang District, but things are not very neat and the store is not big. I wonder if there will be a COS clothing store?
