This mod is a fork of Capes to only show Optifine capes. The Optifine Cape is showed by default. You can also use your minecraft default cape.
You can disable the cape by turning cape off in the skin customization tab.
You can use the default minecraft cape by going into the small cape icon in the customization tab and choosing minecraft cape.

If you dont have the optifine cape, you can get it here https://optifine.net/donate

I basically made this fork because I don't care about any other capes than the Optifine one or the official ones and having to switch between minecraft and optifine in the menu of Capes mod was annoying because I was seeing these useless capes that no one uses and had to pass thru them.
