Tried it. No luck. Inventory is still empty and only thing that remains are links to what was last worn upon logging off the day before.
Edit: Will specify that I've tried it on 4 different clients, and tested with an alt account. Black Dragon, Polarity, Firestorm, and default SL viewers. Cache clearing and inventory stuff did nothing, alt account was perfectly fine and had its inventory intact. From what I'm getting, this is something that randomly happened due to the server issues earlier in the day.
