Ring of minor invisibility - The ring is invisible, and only makes your body invisible, not any of your stuff

But people can see your footsteps cartoon style

Or makes you smell horrible. Yes I just stole this from 'cruelty squad'.

To see something, you need your retina to absorb light, and that makes it visible. Alternative version is ring of invisibility that makes all of you invisible except for eyes.
