Where I come from we call them hula hoops! And this one is see-through jelly pink!
After you have put it on, type "hupla" (yes, I'm staying with convention here so people don't get too confused) to show it and start wiggling!
Works for both male and female avatars.
All products in the above images can be found in my Catalogue.
