"I have warned everyone that I will come for them if they even dare try to copy anything that I'm doing this holiday season," Kim warned.
After tagging several items in the store, Kim thought it best not to share her ideas with the rest of the family.
"I want like a real bark tree. But I won't tell all my ideas out loud, my mom is somewhere lurking," Kim said cautiously.
Kourtney was a little more forthcoming when it came to her holiday decor. When Kris asked her oldest what her Christmas vibe was, Kourtney said she's keeping it consistent.
"I'm going for my same vibe as last year," Kourtney admitted.
But Kim didn't want to go there.
"Well, why don't we not talk about our vibes. That way, no one can like, steal a vibe," Kim suggested.
From a bark tree to a golden angel, Kim is going all out. As for the super-secretive finished product? You'll just have to wait and see.
