Here's a Hogwarts uniform for teenage girls, similar to those we've seen in the Harry Potter movies.

There are two different sets to choose from: A "neat" one with the shirt properly tucked in, and a "sloppy" one with the shirttails untucked. Please note that – since skirt and sweater are two separate items – you'll need to change the skirt if you want to switch from neat to sloppy, not the sweater!

I had to alter the original Maxis meshes for both skirts and jumpers to make these work; the meshes are included in the respective .zip-files. The sweater file includes all four house colours; the skirt file includes both the "neat" and the "sloppy" style.

All items can be found under Everyday. No expansion packs required.
