if there location is hong kong  it red flags me just read there feedbacks nd if the jeans come and there way to small or run about 3 sizes smaller than they should send them back , i take my jeans if i buy them on ebay to a department store most stores will tell you if there real , just hold back on saying ebay , just say can you please tell me if this jean is authentic , it was a gift ,i do not want to return them ,  sales people wil help you , i have had a few pair of jeans turn up as fakes i just set them right back use your dilivery conformation when shiping so your coverd by ebay file thru your paypal ,
