I make a HUD that uses RLV functions to organize your outfits into specific folders within your RLV folder. You basically make a folder for your outfit manager called "LustBaby" (our brand name) and then make a "Strip" and "NoStrip" folder. Put all the "clothes" part of it (things that would come off when you get nekkid - eek!) and things that are part of the avatar (hair, skin, tattoo layers, tails/wings/whatever) that wouldn't come off when you get naked but do come of when you change to another outfit/avatar setup. It's real handy because it only removes things that it finds inside your folders there - so unless you have something that attaches something over the top of something else, the stuff you need to wear all the time - HUDs, flight assist, whatever else - won't be removed. (There are a few other features/enhancements I'm working on too).
Once you have some folders set up - it's three clicks to change into any other outfit (well, maybe four or five if you have more than one blue menu page of outfits set up). But it's a smart little bugger and is pretty good about keeping track of everything for you.
Best of all - it's FREE...

Since it does "Naked" and runs on RLV (restrained life viewer is traditionally for adult roleplay, though there is nothing inherently adult about it) and with all the hullabaloo about the new adult rules - I have flagged is as adult on Xstreet. You can get it on there if you enable adult content and search for "LustBaby HUD". Or if you search my name in world, and visit "Rygel & LustBaby's Workshop" there are buttons and signs with clickie spots all over in there that give out the free HUDs.
(It also has an ZHAO II AO and Avatar Scanner in it which is real handly to clear up a few more hud spots on your screen too).
It can be a little tricky to get it all working right because SL does some funky caching so you sometimes need to recreate the folders in the proper order for it to be able to scan properly, but the help button on the hud takes you to a web page where it's all explained in a way that's easy to grasp and understand what's up.
Have fun with it and if you have ideas on how to improve it (that are practical) please feel free to jot 'em down and send them to me!
