Clothing is often neglected or completely ignored in roleplaying games. Which is a bit of a shame, because clothes can tell you a lot about a person.

Take some time to describe what characters are wearing. The colours, the textures, the cut and craftsmanship, the decorations, the newness or the obvious age - all of these things provide atmosphere and potential hints to the personality or station of the person underneath the clothing. A random stranger met in the street is very different if wearing ragged peasant garb, compared to if they are wearing well-made clothes of silk with detailed gold brocade.

GM: Jabba slumbers in his chamber. You see Princess on the throne platform, obviously his slave.
Luke: How so?
GM: Well, uh, she's chained up and dressed as a slave.
Leia: Ah, like Shmi. Shapeless sackcloth sort of thing?
GM: Yeah, um... something like that.
GM: Princess, you sense something odd about the frog-things in Jabba's snack bowl.
Leia: What, they don't want to be eaten? Big surprise.
Luke: I sneak up to Jabba. <roll>
Bib Fortuna: Hey, good buddy. Got your back.
Luke: What? Wedge??
Bib Fortuna: Down low, my man! The one and only.
Luke: Wow, nice uh... shapeshift.
Bib Fortuna: Nah, buddy. This is just a rubber suit. I'm human inside here.
Luke: Aha! So you're working for Jabba!
Bib Fortuna: Undercover.
