快时尚指仿照高端时尚品牌最新的款式，以低成本、快速生产的模式制造出来的服装产品。
"Unlike conventional clothing companies where designers plan their new lines every season, fast fashion retailers design, manufacture, and release new products ad hoc, whenever new trends appear," explains a report on fast fashion funded by the Samsung Economic Research Institute.
由三星经济研究院资助的一项有关快时尚的研究报告指出：“传统服装公司设计师会为每一季设计新的款式，快时尚商家则不同，他们随时都在设计、加工并发布新产品，只要有新的流行趋势出现。”
