Yeah it's nice to know it's not YOUR fault hey Dee! You know, you must wonder if people are thinking - well if she just did this then her daughter would be fine! Christy gets that a fair bit too, it's not fair because even if that strategy worked for them and Ashlea it doesn't work for you and Ash.
Keep going, you are doing well and it's great that she behaves at school, etc. at least you know she can. She obviously feels very comfortable with you (!) and able to explore whatever her issue is!
What does your ex-idiot,oops ex-husband do when she does this? or does she not do it for him? which would maybe rule out the sensory thing, or maybe ? it is your washing powder, or something??? It couldn't be that simple! Yeah, I think asking her when she's calmer what it is about the clothes that she didn't like would be good. Difficult for her to put it into words, but keep going!

You're a legend mummy!! She is SOO going to reward you even more when she's older, you guys are going to be great mates. Is she anal? control freak at all?
