This bug allows you to equip items that you do not own from the character creator in Minecraft Bedrock edition. To do the glitch you start of by heading to any of the options you want, tops, bottoms, hats, etc.  You must select the item, but right as you select it spam circle, if done correctly you should be wearing it without buying the item. I asked friends if they seen the item on me and they did, I managed to recreate this several times, However. After you restart your minecraft or switch to old minecraft the skin will fail to load because you do not own the items. I have not tested this on other systems. In the images I have provided you can see I have selected an Item I have not bought.
