How do you represent different system members in physical space?

Usually, different system members have different appearances. Sometimes, different system members may have different bodies to each other-- even as far as having different gender or species. But with only one physical body, it's hard to represent or tell every members with the same body in physical space. So, how does your system handle that?

How do you tell apart or represent different system members in physical space? Do you only differentiate in headspace-- each members' physical form exist in headspace while the real life self remains the same regardless of who's fronting. Maybe you use subtle cues like arm ring color or necklace. Or maybe you use different clothes for different headmates-- though that would be difficult if you switch front while being outside.

Perhaps it's the different behavior like walking style, gestures, or manners. Or, just through the different personality each system members may have while fronting.

For us at least, we don't differentiate that much physically-- we like to think our body is separate from our headspace identity so it doesn't need to match our headspace form. We're also closeted about being plural, so we don't try to cue the fact we are more than one person.
