I personally like doing this when to comes to outfit changes:
@CHARACTER is dustoff_loop
@pause for 0.5
@CHARACTER changes into Outfit1
@CHARACTER is shiftweight
^^^The following animations are in INK but it works the same for LL, the pause would allow the character to “dustoff” for a bit before their outfit changes and the “shiftweight” is what I put after they change so it wouldn’t look like the character is constantly doing the dustoff animation, hope this helps! You can of course change the pause and animations to your preference!
