Apologies in advance for what will probably be quite a long post! cocochops was asking about Project 333. It's a simple concept - you have 33 items of clothing (certain exclusions and you can modify to suit) for three months. Pretty simple, but it's surprisingly deep.
I came to it via the minimalist threads in Good Housekeeping, and also the frugal fashion threads here in S&B (worth digging out and reading). I started just after Christmas, largely because I thought it sounded ridiculous, and I couldn't/didn't want to do it. You just pack away or put to one side your non-33 items, so you're not making any permanent decisions.
I had a fair amount of clothes (although nowhere near as many as some S&B posters). For example, I had four pairs of jeans, none of which I liked or really wore. None of those were included in my first two seasons. One was in this last season (because I'd lost the fat around my middle, they fitted better. building like you, I'm paleo/primal)). I have now charity shopped the other three pairs and bought a pair that I love and fit me.
However, psychologically the project has been so beneficial. I feel much lighter and less guilty about all the clothes I had, but never really wore. Or felt I 'should' wear, but didn't feel good in. I also realised that many of my clothes were wrong for my lifestyle. I had too many going out dresses, but I never go anywhere formal - pub, curry or going to see a band is my social life, and that's how I like it.
It's also made me realise what I like about clothes - good fabrics, good fit, good colours. It's what tipped me into having my colours done, and it's a real joy now to have pretty much everything in my wardrobe go with everything else. At the beginning, it felt like paying so much attention to my clothes was somehow shallow and unfeminist, but these things do matter. I read a book recommended by frugal fashionista called You Are What You Wear, which was really insightful. Also a blog called recoveringshopaholic.com/. I am most definitely not a shopaholic (I actively dislike shopping).
I would definitely recommend Project 333, but then I am an advocate of minimalism and simplicity parenting. Also, from an environmental point of view, it's crazy how many unworn clothes we all have in our wardrobes.
