Clothing rewards
In every Additional Investigation in the game, one of the suspects will reward the player with a set of clothes. (This does not apply to The Death of Rosa Wolf and Corpse in a Garden, however.)

Most rewards are different depending on the player-avatar's gender. For instance, in Under the Knife, Joshua Kempe's "Fashion Hairstyle" has two versions: if the player-avatar is male, they will get the male version; however, if the player-avatar is female, they will get the female version. The tables below include both versions of such clothing items, even though some of them may noticeably be the same for both genders (be it for its name and/or appearance).

If you change your avatar's gender, your existing rewards will not change for those of the opposite gender, and you will not be able to use them. So if you plan the change, do not put it off. Also, do not try to change the gender temporarily in order to get a reward you like more, as it will be unusable when you switch back.
