I'm wearing my Cuffs, but my HUD says I'm not
This is most likely an SL sync issue.
Try the following till it works.
- Detach your Cuffs, and rez a new set from the HUD, one or two at a time
- Restart your HUD and try again. HUD Menu > HELP > restart
- Get a new HUD and try again. Or HUD Menu > HELP > new HUD
