You'll be able to visit the hairdresser with a girl on a date to change their hairstyle & colour. I've also added a hair & beauty player skill & job category, and although it's not implemented yet, I plan to make it possible for you to do this yourself if you have the right skill level.
Cooking will be in the next update, albeit in quite a basic form (triggered via home upgrades) that will likely be expanded upon in future. Similar to hair & beauty, there is a cooking skill connected to the new jobs system that will improve what you create with this.
More interactive clothing won't be in the next update, unfortunately. That might have to wait until the personality update!
