While fast fashion has proven very popular with consumers, critics allege that its producers and retailers take liberties with others' intellectual property, with the most flagrant violations approaching the level of outright design piracy. Others take issue with fast fashion's rapid production cycles, which surpass traditional fashion seasons by introducing new collections in monthly, biweekly, or even weekly microseasons. Some argue that this practice cheapens the professional value of fashion design and contributes to exploitative labor practices and a wasteful culture of disposability.
