Yeah, as long as you don't try to claim you're law enforcement they can't legally get you on those outfits. You can look up pictures of them, go on evike or another airsoft shop, and you match 99% of their different outfits. At most you need to go elsewhere for matching denim.

Kidnapping and false imprisonment might be on the table though, depending on the other person. There's also conealing/falsefying your identity in a court building, which is iffy in some jurisdictions.
