I remember this piece of CC vividly but cannot find it. I did find another similar item for download here on MTS but it doesn't have the same door.

It wasn't a real closet (i.e. using AL tuning) but was basically some hanging clothes with a door which could fit into a 1x1 space.

The door it used was the Yankee Four Score Door in white.
(this is the shape of that door for reference)

It would be nice to find this again as I do like to have smaller closets in my smaller homes, and I feel like I need more variety than having just the one.

If you know of any other custom closets (whether just wardrobes made to look like closets, or ones based on the 2 tile AL ones) besides the one I'm looking for please let me know!! I always like to have a bit more variety going on in my game.

I think you're looking for Marmy's Single Built-in Closet.

I also really love the Shakeshaft's Louvre Sliding Closet, too.

I also use the base game clothes racks and make my own closets.

Thank you so so much!! I knew I'd found it on here somewhere but my searching wasn't getting me to it.
