It's either the one from MATY, or the "wardrobe wrangler" object that comes with the Insimenator mod. They both do much the same.

here for other verisons)
If it is the folded up clothes then it is the wardrobe adjuster within the inSimenator mod. It can be found here
here on this site. That being said
heed the warnings on that page prior to downloading the mod as it is
entirely unsupported—so don't ask for updates or fixes. I don't mind assisting for occasional mild issues so feel free to pm if you need a little help installing it.
I have all the EP's & Sp's to Mansion's and Garden and to date still use this mod without any issues.
In addition to the (supported) tool Theraven mentioned there's also the "Sim Manipulator" (suggested on the page in the link above). I've never used it but it is still supported and it's usually recommended to use supported mods in your games.
