英国采购需求：定制瑜伽服、定制连帽衫、定制运动服、定制T恤、批发背心、批量运动文胸

I hope this message finds you well. I'm a new entrepreneur based in London, UK, and I'm keen on starting a business in the casual leggings market. I'm particularly interested in sourcing leggings suitable for both warm and cold weather, specifically for women and children. I'm looking for suppliers who can guide me through the process, as I'm still learning the ropes. Could you please provide me with some information on how your company typically collaborates with beginners like myself? I'm interested in understanding your minimum order quantities, customization options, pricing, and any support you can offer during my initial buying experience. It would be great to know how you handle shipping and delivery as well. Thank you!
