I'm new to SL, but signed up for premium membership for the new house. My avatar had the basic t-shirt and underwear that wouldn't come off, so I purchased a really nice male skin. Problem: The new skin is in my inventory, I'm (Avvatar) in the master bedroom of my home and I don't know what to do. I tried to get the new skin to attach to my avatar and it suddenly had a box stuck on his hand! What do I need to do to make the transistion? Thanks in advance for any help!
