How can I make something similar to this? Been looking everywhere but i cant find any help. (videos or just help in general will be great!)
Make the selection UI,
On image click, you should do something like this,
use something like:
for i, v in pairs(character:GetChildren()) do
if v:IsA("Hat") then
v:Destroy()
end
end
and then add the hat they clicked on,

its the same method as this post i just made over here
side note if you are putting on roblox catalog hairs if you just parent the accessory to the character it will snap into place
