Ryan wearing a belt
A belt was a long, narrow strip of material fastened around the waist to keep pants up.
ECS Fortunate first officer Matthew Ryan was wearing a belt. (ENT: "Fortunate Son")
Odo used to wear a belt, but due to being a Changeling and having no need for it, gave up wearing it. Kira Nerys once said that Odo looked good wearing it, so he shapeshifted it onto himself. (DS9: "Crossfire")
