So I'm still pretty new to Second Life so bare with me here. I'm having some issues putting on new clothing on a new avatar I got. He puts on the default cloths for the mesh avatar I had, but I can't put any other clothing on him. I know you can't put on new clothing on mesh avatars, but like I said, this is one I just bought and I even tried putting them on in sequence order like underpants first then pants, etc. Is there something I'm missing?
