If you change your love interest's default hairstyle before the date in the Date Closet, that will become their permanent hairstyle. A new wardrobe will also be created for the love interest, similar to your own wardrobe, allowing you to customize hairstyles, accessories, and facial hair.
You can customize the appearance of your love interest prior to taking them on a date via the Date Closet. As the bombshell of this season, you’ll have an opportunity to do this very early in the game.
Wardrobes will differ based on the love interest's gender, and each wardrobe will have a pool of options available at the beginning of the game. New outfits featured in Date Closet will also be added to the wardrobes, allowing you to change the looks of all love interests, whether you’re going on a date with them or not. This wardrobe option can be accessed through every individual love interest's profile. For non-playable characters that change from friends to lovers, this option will also become available in their profiles after the conversion happens.
