There is no one-size-fits-all answer to this question, as the required uniforms will vary depending on which league you are playing in. However, in general, most leagues will require players to purchase their own uniforms. This typically includes both a jersey and pants/shorts, as well as any other required gear such as cleats, mouthguards, etc. While the cost of these items can vary depending on the quality and brand that you choose, you can expect to spend around $100 or more on a complete set of uniform items.
