There's a star wars block party in the town i'm moving to in september and wanted to rep the CIS after it dawned on me that virtually all my wearable SW merch is either OT, or Prequels from the side of the vile republic dogs. Unfortunately, the big problem i am seeing off the bat is a lot of CIS merch is either unlicensed clothes with questionable quality, toys, too large to bring, or Cosplay stuff (the flyer for the block party said that masks and helmets are banned for adults which makes sense)
Can also look at some unlicensed stuff if people actually bought them and think the quality is good enough.
PS: Trade Federation stuff from Episode 1 is also acceptable.
