Which layout are you referring to?
For stat increases, complete all side missions with the girls.
Those will give you stat boosts:
Gracie = Intelligence +3
Luna = Agility +3
Isabel = Charisma +3.
You can gain +1 Knowledge from the book bought in the Market, during Nimble Fingers.
I think the Promotion Event will also give you some stat increases but, other than that, all stats are gained from clothing.
Most of the better items are rewards in Contracts, WT in OP shows how to get them, but some useful stuff (like the Long Coat) can be purchased.
When you've gained all Special clothing & got the best gear equipped, your stats should look something like
this.
