I believe the only way to equip someone else with a jumpsuit accessory is to tear their clothes off and manually put the accessory (a scarf, medal, tie, etc.) on the suit. I think it would be a neat feature to have it so when you click someone with an accessory, it would start to place it on their outfit as if you were placing it on like normal clothing items. This would make simple things like a captain awarding medals more interesting than just handing a medal to someone to pin on themself, instead offering a fun RP scenario of the captain pinning the medal to the person personally, along with other scenarios with other items.
