I'm looking to place an order for plain T-shirts without any branding or logos. The key requirement is that these shirts should come in a variety of colors to give us a broad selection.

In addition, I would appreciate information regarding the fabric quality, sizing options, and minimum order quantities. It's essential that the T-shirts are versatile and suitable for different occasions. Let me know about your pricing structure and lead times for fulfillment as well.
