How I can wear for ex: Scarf and Helmet in game that I made on Roblox?

I am not sure if I fully understand but I think you can add an accessory to the character and it would wear it although you have to put it in the right place

That's great idea. But I mean it like, I have a Helmet giver and a Scarf giver. If I take the helmet, then I can't take the scarf. Do you know how to fix that?

You can wear multiple accessories. And they should auto position if they are made right.

But, When I wear hat, then I can't wear accessories. Can I add you on roblox or discord and have a talk?

You could just have it be a part and a mesh inside the part that you attach to the player, that way you don't have a limit on how many hats or whatever you want to add to the character.

You could just have this as an accessory, then put it into a place like serverstorage, then when someone joins, clone it and add it to them.

But It is not mest, It is Hat Giver.
