What I think some of the clones would wear for Halloween:
Rex is obviously wearing a t-rex suit against his better judgement.
Bly did a couple’s costume with Aayla. They are Jack and Sally and it’s adorable.
The entire wolf pack dressed up as Plo and he had a proud dad moment.
Fox did not want nor plan to wear a costume but Thorn and Thire got him a Fox Mcloud costume.
Cody and Obi wan also did a couples costume and it was Sherlock and Watson.
