The bodies and the cut and sew elements (robes, bandoliers, etc.) are really the most expensive parts for this set. It may just seem like a simple robe but there are inner robes and outer cloaks with hoods that are adjustable which equals something that really isn't simple in nature when creating it. Then you factor in the bandoliers that go across their chests and another with a pistol holder and there's even more cut and sew elements to the set.
Adding stands would have added more dollars to the final SRP for sure. If folks are baulking at $220, I'm going to guess higher then that with stands would have any more baulking? Just a guess though.
Just sharing some tidbits with you and all here. Not trying to convince people either way (i.e.: Buy or don't buy) but just passing along some info.
And no, not my call to make of stand vs no stand, ha! I love that gif...always cracks me up when I see it, ha!
