This is the style that I use. I like this headless and armless version best by far. It's simple and lets the jersey speak for itself... has a very classy look to it. This one is from an etsy seller, and the price is tough to beat....

It is adjustable, and can extend between 32" and 56" tall. Once the internet page opens, scroll down, and you'll see that the base and collar are available in black, silver and bronze. It is perfect for any jersey, but if you want to display the pants, you'll need a full body mannequin. And if the uniform includes a hat, you'll need one with a head. But then it starts getting kind of creepy.
