Oh.

So far I’ve got Adam or Don, but I don’t know which one.

Don is a liar and Carl id not.

But Adam is a liar too.

I’m going for Don.

The only distribution of original costumes that works is :
A: T
B: F
C: F
D: T
E: F
F: T

A is a tree and says it was stolen by a flower, so it was stolen by a tree.
C is a flower and says it wasn’t F, so that leaves A and D.

D is the only one who made specific accusations which he must have known were not true, so he must have been the culprit.
