I love this idea and one of my clients who has ADHD decided that was a great way for her not to get overwhelmed while dressing, and is using it quite effectively, although she keeps some more splashy pieces for weekends.
I’m too eclectic I think, or maybe it’s that I spent most of my earlier years trying to blend in by only wearing solids and basic colors. Once I broke out into more self-expressed clothing, I found that I really enjoy it. Fortunately, I’m really decisive though.
I think that you’ve gotta go with what works for you though, and it sounds like this really does!
