You can write your topic however you want, but you need to answer these questions:
What do you want to achieve? Keep it simple and clear!
I want to make a gui that when the player clicks, it then changes what clothes they are currently wearing to their avatar’s original clothes.
What is the issue? Include screenshots / videos if possible!
I don’t know how to.
What solutions have you tried so far? Did you look for solutions on the Developer Hub?
I have tried YT and Devforum
