I went around collecting all of the items I could find around the map. I noticed that if you've started either the Bunny or Puppy quests, picking up certain items while having those quest items locked on will mess with things.
For instance, when you have the Puppy Collar on, and you find the Armbinder in the Hedge Maze. She immediately puts the binder on, and neither item cannot removed as they're supposed to conflict with each other; and you cannot escape from where the Braces are found. This also clashes with Handcuffs, once equipped, they can't be removed.
During the Bunny quests, I collected one of the Gowns, and the Gown would become part of the character model from then on, no matter what, even when unequipped, and wearing other clothes.
Next up, when hiding in a Barrel, I tried using an emote, and it was able to work.
