I was playing Minecraft on the Xbox and I unequipped my founders cape and when I went to put it back on it just disappeared. I've spent the past half hour trying to get it back only to come to the conclusion it's impossible to get. How I do I get it back

So basically I was playing Minecraft when I decided to change my character a bit in the character creator . I went to unequivocal the founders cape, which I've had for quite some time now and when I went to put it back on it disappeared. I've spent so much time trying to get it back and it's really pissing me off. Is there any way you could help me get it back.
