Custom Capes

I think that Mojang should add custom capes to Minecraft. I still think that for some events, for example :Minecon and the 15 year anniversary Creeper Cape should be special to that event, but other capes that everybody can have. Some free, like simple designs, for example: a pig, a pickaxe, a grass block, or other in game items. Other capes could either still be free, or cost Minecoins or money. Examples for Buy able capes or capes that aren't free could be: a Star Wars Logo cape, a basketball cape, a USA flag cape, or other designs. The capes could come in different Marketplace packs you can get for free or with Minecoins and/or money.
