Judy is one of the oldest figures. (She came with Poser5) And only Judy casual survived. Judy herself has gone.

You might find some stuff for Judy if you go and search the free-stuff area's and the Marketplaces dating some 10 years ago.

All more modern figures can borrow clothing from each other using Wardrobe Wizzard or the fitting room, because they are more or less grouped the same way. Smith Micro has some great Fitting room tutorials on YouTube to "cross-dress" figures and clothing.

Personally, I always take the figure and the clothing into Blender to do an initial "fit", and then use the Fitting room to transfer the rig. Video1 and Video4 on my tonyvilters YouTube channel might be of some help creating your workflow. (Mostly for obj file import and export and for obj file quality checks.)
