I'm going to try Project 333, and wondered whether anyone was already doing this, or might like to join me?
I'm just finishing the book atm, and, while I'm not an expert, my understanding is that you choose 33 items and only wear these for 3 months. I'm planning to stick to the rules pretty closely, although I don't think I'm going to count the jewellery that I wear every day or my glasses. The book pretty much encourages you to break the rules in a way that works for you anyway.
I've nearly finished my list of 33 items - apparently underwear, loungewear, and workout gear aren't included. I'll post my list when I'm done, although this will obvs be suitable for my WFH and non-party-going life.
