SEAMDANCE is a gym wear, activewear, yoga wear and sportswear manufacturer in Xiamen, Fujian, China. SEAMDANCE has been in activewear since 2018, and the team behind it worked in OEM contract manufacturing before that. The company that contracts orders today, 厦门西丹思供应链管理有限公司 (Xiamen Seamdance Supply Chain Management Co., Ltd.), was registered in Xiamen in 2026, as its business licence shows. Our own factory has 150 sewing machines (53 single-needle lockstitch, 64 overlock, 20 coverstitch, 10 flatseamers, 3 buttonhole), 6 pressing stations and seamless circular knitting machines, with a three-person development team that develops about 800 new styles a year and can turn a sample in as little as 3 days. Cut-and-sew fabrics are knitted and dyed by our partner mills. Together with our one-stop service, that covers a whole range — from leggings, sports bras, sets and seamless styles to jackets, swimwear, tennis wear, bags, yoga mats and accessories — with the fabrics and certificates each order requires. One order, one quality standard (final inspection to AQL 2.5), one team accountable. Factory visits by appointment; live video walk-throughs on request.
