Item You Most Regret Not Getting When It Was Available?

Could be a doll/outfit/accessory/furniture.

I was on Facebook marketplace today and saw someone selling the World Traveler in France outfit for some crazy price, and it made me realize how much I wish I had just gotten it when it was still available. The pieces are so good! I also wish I had gotten more of the LoveShackFancy collab while it was still available (I only have the pink skirt, which I'm obsessed with). What about y'all?
