State-based dialogue side-images

[Blueworx]

Seems like an easy one, but I couldn't find anything related. The player character in my game will have dialogue like you can see above, and he will be able to change his outfit pretty much all the time. Meaning that he could wear pretty much everything while having said dialogue. And you can probably already see the problem, especially when there is a lot of dialogue and a lot of outfits.
Is there a function or script to choose the side image based on a variable (state, flag, switch, I'm not choosy)?
