I like the mod Girl_Alex bu Adarin http://www.nexusmods.com/stardewvalley/mods/387/? but noticed it was only the images and not the dialog so I decided to try my hand at rewriting all the dialog to refer to Alex as a she instead.

There are still a few things missing like editing the bedroom door (I haven't figured out how yet) but I believe I got most of it.

If you see anything I missed, feel free to let me know.

I plan on making this for Adarin's Elliot Girl as well.

INSTALLATION

Move the Characters Folder from the mod into the Content folder of the game.
Let it overwrite any files and there you go.
Be sure to back up any files in case you want to switch back.

To uninstall, just move the original files back and let them overwrite the mod.

Also check out the dialogue mod I made for Elliot_Girl by Adarin http://www.nexusmods.com/stardewvalley/mods/396/?
