Notes*
- Add twintails on negative for the medium or long hair if the desired result is to not have them, as the model is quite often leaning towards it regardless.

- The Graduation dress doesn't work as intended with a blue hair ribbon paired with a pink dress ribbon and instead will only produce one of the two.
