noob question...not sure how to use new jeans.

I notice i have this items in my steam inventory…blue jeans…and shirt with a g on it…does this mean i am capable of making it? No bps in my tab list

yeah you can make them but you need the bps first.

So you need them on both steam and server inventories?

As i understand it, yes. Get the Tshirt bp, and you should get the option to make the ‘g’ shirt once you have it.(the ‘g’ is the Garrys Mod shirt)
