After playing through a few times and getting married with all bachelors, I've been thinking about making a genderswap mod. Drawing those new male sprites for the girls really drove me crazy but I still got over this and finally finished this mod (hooray for me). Since I don't know how to change the dialogues, it may seems a little weird when the male version bachelorettes saying some girly things. How to install: Download the Portraits.zip and Sprites(Characters).zip and then unfold them. Copy the new portrait files and replace to the game folder - Stardew Valley/Content/Portaits. The sprite files go to Stardew Valley/Content/Characters. Don't forget to backup the original files.
