Has anyone worked with Zaoyi Garment for wholesale bras or custom bras? I'm considering partnering with them for my boutique and wanted to know about their quality and service. They specialize in bras and accessories, and I’m particularly interested in their customization options. How is their sizing accuracy, material quality, and production time? Also, do they offer any design assistance if we want to create unique styles? If you've placed bulk orders with them before, did you find their pricing competitive?
