That seller's photos are stolen from everywhere. The ones stolen from Taobao could be handwaved as the unauthorized reselling, but the ones stolen from Mary Magdalene (an exclusive Japanese limited-run brand) and a cosplayer who makes her own costumes? Definitely not representative of what you will get in the mail.
Also, the items with photos stolen from Taobao? There's a nautical coat by CMLoli, which CMLoli sells for ~$67 USD. This Ebay seller has it listed for $120.66...
Stolen photos from:
Mary Magdalene (very limited-run, high-end brand)
Arisa Mizuhara (cosplayer who makes her own costumes)
ICOS (including items that ICOS already removed!!)
That's at a glance, just skimming the logos and photography I recognise. And given Arisa Mizuhara's stolen photo, I imagine the other cosplayer photos are also stolen.
