Castoff clothes are garments that have been discarded or donated by their original owner. Synonyms for this term include secondhand clothing, thrift store finds, hand-me-downs, used apparel, pre-loved items, recycled clothing, and vintage pieces. These terms can evoke a sense of sustainability and low impact consumption in contrast to fast fashion and disposable clothing. Purchasing castoff clothes can be an economical way to update one's wardrobe while reducing waste, and can also provide unique and individualized fashion options. Additionally, donating castoff clothes to charitable organizations or eco-friendly fashion companies can help reduce textile waste and support social and environmental causes.
