Question??? [Clothes Tool] Devblog 18

Clothes Tool.
In the Devblog 18 garry talk of this tool. how and where I can use it?
thanks for you help =D

i think that part of the devblog is more an insight into tools made by the team to help with development so we get to see how things are progressing, and what their time has been used on. i don’t believe it is accessible by the public.
