美国采购需求：运动裤、慢跑裤、运动服、瑜伽裤、健身裤、紧身裤

I'm looking to source school uniforms for our upcoming academic year. We need a variety of styles and sizes to accommodate different age groups, and I'm particularly interested in materials that are durable and comfortable for everyday wear. Could you please provide details on your available options, including fabric choices, color palettes, and any customization possibilities? Additionally, I'd like to know about your pricing structure, minimum order quantities, and lead times for delivery. Thanks!
