There was a stealth suit topic. It was better.
We all have the belt already - 9 blocks selection.
I'm not sure if this truly is "better" as you claim, but I couldn't find anything on the forums about a "stealth suit". Could you try to find a link?
Also, why would you need it to be a suit? More importantly, how would you be able to code it so the four armor pieces would have overlapping or meshing functions? I don't know a whole lot about code, but a single item sounds like it'd be a lot easier to code than multiple items that compound upon or require each other, if that's indeed how it works. If that's not how it works, it seems slightly redundant to me.
