My last Founders cape completly gone after equiping other skin

Hi, I have a problem.

Recently i had last Founders cape on my main skin, and i wanted to equip skin, because i had no skin equiped.

Last 1-3 Years i noticed, there is no way back to equip Founders cape.

And last thing, i didnt notice, there was a way to recover the cape.

Im so dissapointed about my rare cape that i lost.

I would be so happy to have it back.
