Selling socks in the live broadcast room and sending three pairs for try-on means that on some e-commerce live broadcast platforms, some sellers will sell socks in a promotional way and provide try-on services. Specifically, after the buyer buys the specified socks, the seller will give away three pairs of try-on socks for free, so that the buyer can try them on before deciding whether to buy them. This promotion method aims to let buyers better understand the quality and comfort of socks and improve their confidence and satisfaction in purchasing.

Socks are a kind of clothing worn on feet, usually made of cloth, cotton, wool and other materials.
