Thanks for linking, cherid87120. As much as I like the lamp version, I'd love to see a tree with a "Decorate" group function - maybe some theme choices like the house lights have - white, multi, or blue lights.
Agreed perhaps they might make one for the store as a premium content item but this close to Sims 4 it might be good to mention it to the Devs. on that forum too.

If you look on the sims resource, there's some custom content Christmas trees that you can decorate yourself through using buy mode, but that's as close as you're going to get for decorating your own tree.

I agree that it would be nice to be able to decorate your own.

Agreed and also a fiscus tree. I have some fiscus trees artificial ones in my house I light up year round with white lights.
