Is there any way to get more ouftit slots ?

I absolutely adore this game and part of my enjoyment comes down to fashion looks. Having an ouftit for every occasion is great. And there is so many of them and incoming. I'm wondering if there is a way to expand the limit ? As 7 slots feels pretty limited compared to what we can do with buildings (build everything everywhere). Do (chinese) players have an answer on this topic ?

Thank you.
