^ As mentioned there is an item available to change your physical appearance.
Thinking over it, as much as I want to change my race I don't think there should be an item for it. Rankings in crafting would completely be messed up because many people can change to a zumi, anuran, or bear where they would rank in the top 20 while if they were human they would rank much lower than that. People would switch races to make money via the ranking prizes and this can be a hassle for the GMs to alter your race and update the stat changes (passives) and name in the achievements ranking.
It is a bit unfair for the people who played when humans were the only available race, however if someone really wanted to change race, they would put in the effort to restart over as a new character.
As for the gender change item, I don't think that is needed because if you came into the game as a gender, changing it later on would appear to be for dubious reasons. Its just a trivial matter and one would expect you to pick the right gender for you upon entering the game.
Though with your item of changing physical cosmetics, I hope that further options are added to the makeover kit. Maybe being able to access more hairstyles, colours, and so forth.
