If the Playboy trademark originally belonged to the Tmall store, then it cannot be said to be fake, only low-quality clothes. Generally, you need to take it for quality inspection to see whether the ingredients, water fastness, etc. meet the national standards. If not, you can complain to Tmall about this store with the inspection report
