Project 333 is Courtney Carver's challenge to dress with 33 items or fewer for three months. Clothes, shoes, accessories, jewellery and outerwear count; underwear, sleepwear, home-only lounge wear, workout-only clothes and sentimental jewellery you never remove don't. Box up everything else and choose again next season.

Project 333 is a minimalist fashion challenge created by Courtney Carver: you dress with 33 items or fewer for three months. Clothing, accessories, jewellery, outerwear and shoes all count toward the 33. Underwear, sleepwear, lounge wear you only wear at home, workout clothes you only wear to exercise, and a wedding ring or other sentimental jewellery you never take off do not.
Everything outside your 33 goes into a sealed box, out of sight, until the three months are up. Then you choose again for the next season.
The Project 333 rules
Carver set out the rules on her blog, Be More with Less, in 2010, and her rules page still lists the same core points:
| Rule | What it says |
|---|---|
| When | Every three months. Her seasons begin on 1 January, 1 April, 1 July and 1 October, but you can start on any date. |
| What counts | 33 items, including clothing, accessories, jewellery, outerwear and shoes. |
| What doesn't count | Underwear, sleepwear, lounge wear worn only at home, workout clothes worn only for working out, and a wedding ring or other sentimental jewellery you never take off. |
| How | Choose your 33, box up everything else, seal the box with tape and put it out of sight. |
| Wear and tear | If something stops fitting or wears out, replace it. |
The rules also describe the 33 as a wardrobe you can live, work and play in for three months. Take that line seriously. If your selection leaves you cold at the bus stop or underdressed for a client meeting, the selection needs another look.
What counts toward the 33, item by item
The categories are clear. The edge cases are where people get stuck. Carver's own sample lists on her blog put bags, belts, scarves, hats, gloves and sunglasses under accessories, so all of those count.
- Coats and jackets count. Outerwear is named in the rules, so a winter coat and a rain jacket are two items.
- Every pair of shoes counts, from trainers to boots to sandals.
- Bags count. An everyday bag and a weekend tote are two items.
- Jewellery counts, apart from sentimental pieces you never take off. A watch isn't mentioned by name, so treat it as jewellery unless it never leaves your wrist.
- Workout clothes are free only while they stay workout clothes. Leggings or a hoodie that also go to the shops or the office count.
- Lounge wear is free only at home. Once it goes out for coffee, it counts.
- Socks and tights aren't named in the rules. Decide on day one whether you treat them like underwear, and stick to it.
- Uniforms and specialist kit, such as a uniform your employer issues, ski gear or a wetsuit, aren't covered either. A sensible approach is to leave out clothes you have no choice about wearing and write down what you've excluded.
Where Project 333 came from
Carver wrote the rules in 2010 and began her own first three-month, 33-item experiment on 1 October that year, as she recalls in a look back written 16 years later. Her publisher describes the motive plainly: an expensive shopping habit, little satisfaction from what she bought, and a wardrobe that kept growing.
The challenge spread through her blog and readers' own write-ups. In 2020 she published a book on it, Project 333: The Minimalist Fashion Challenge That Proves Less Really Is So Much More (Tarcher). It sits alongside several other numbered wardrobe rules, which our overview of capsule wardrobe rules compares side by side.
How to start your first Project 333 season
- Pick a start date. The first day of a season is tidy, but any date works as long as you mark the end date three months later.
- Write down the next three months. Count workdays, note the likely weather and list fixed events: a wedding, an interview, a trip. Four office days a week over 13 weeks is about 50 workdays, so work clothes deserve a large share of your slots.
- Start from what you already wear. Last week's laundry basket is a more honest guide to your favourites than the wardrobe is. Then add what your plans require, such as a warm coat if winter is coming or one outfit for that wedding.
- Count everything. Include shoes, bags, belts and jewellery. Expect to go over on the first pass, and cut the pieces that only work with one other item.
- Box up the rest. Seal it, write the end date on the lid and store it under the bed, at the top of a cupboard or in another room. Not seeing the alternatives every morning is part of the point.
- Pause shopping. Carver's guidance is to replace things that wear out or stop fitting, and to skip sales and browsing until the season ends.
Keep the list of your 33 somewhere you'll see it, on paper or on your phone. Photos help if you like planning outfits visually. FitWardrobe is our app, and it isn't available yet; when it opens, it will suggest outfits built only from the clothes you've added, which suits a fixed 33, though sticking to the number is still up to you.
A sample 33 for a cool-weather season
One example split on Carver's site is 21 clothing items, 5 accessories, 3 pieces of jewellery and 4 pairs of shoes. Here is how that could look for autumn in a temperate city. Swap the pieces for your climate and your work, and keep the counting honest.
| Category | Pieces | Count |
|---|---|---|
| Outerwear | Wool coat, waterproof jacket, denim jacket | 3 |
| Knitwear | Grey crew-neck jumper, navy cardigan, black roll-neck | 3 |
| Tops | 3 plain T-shirts, 2 long-sleeve tops, 2 button-up shirts, 1 sweatshirt | 8 |
| Bottoms | Dark jeans, black trousers, beige chinos, grey wool trousers, a skirt or a second pair of jeans | 5 |
| Smart pieces | Navy blazer, one occasion piece (a dress or a dark suit jacket) | 2 |
| Shoes | White trainers, leather boots, smart shoes, waterproof walking shoes | 4 |
| Accessories | Everyday bag, belt, scarf, beanie, sunglasses | 5 |
| Jewellery | Watch, ring, necklace or earrings | 3 |
| Total | 33 |
Twenty-one clothes looks thin on paper, but many of us already live on fewer clothes than we own: WRAP's 2022 survey of more than 6,000 UK adults found that about a quarter of the clothes in their wardrobes hadn't been worn for at least a year. And eight tops and five bottoms in a shared colour palette give you 40 top-and-bottom pairings before you add a jumper, a jacket or the blazer.
A sample Project 333 list for a work season
Here is one way 33 items could cover three months of office or hybrid work. Swap pieces to suit your dress code, climate and whether you wear skirts, dresses or neither; the point is the balance between categories, not these exact items.
| Category | Items | Count |
|---|---|---|
| Outerwear | Wool coat, light trench or rain jacket, navy blazer | 3 |
| Tops | White shirt, light-blue shirt, striped shirt or blouse, navy fine knit, grey fine knit, white T-shirt, black T-shirt, cardigan or overshirt, one smarter top for evenings | 9 |
| Bottoms | Charcoal tailored trousers, navy tailored trousers, dark jeans, cream trousers or chinos, a skirt or a second pair of chinos, relaxed weekend trousers | 6 |
| Extra layer or dress | A work dress, or a second blazer in grey | 1 |
| Shoes | Loafers, white trainers, ankle boots, smarter flats or derbies, weather boots | 5 |
| Accessories and jewellery | Work bag, weekend tote, two belts, watch, scarf, two pieces of everyday jewellery, sunglasses | 9 |
That makes 33. Underwear, sleepwear, home-only loungewear, gym kit and sentimental jewellery such as a wedding ring don't count, as the rules above set out. If you would rather see the outfits inside a list like this before boxing everything else, a capsule wardrobe planner can help you plan your 33 pieces.
What happens to the boxed clothes
They wait. Nothing in the rules makes you get rid of anything. At the end of the season, open the box and sort what's inside into three piles:
- pieces you missed and want in your next 33
- pieces you forgot you owned
- pieces you're unsure about, which can go back in the box for another round
The middle pile is the easiest to donate, sell or swap. If you didn't think about something for three months, you have your answer.
Project 333 vs the 3-3-3 rule
The names are close, and searches for a "333 rule" mix them up. They are different challenges:
| Project 333 | 3-3-3 rule | |
|---|---|---|
| What you keep | 33 items | 3 tops, 3 bottoms and 3 pairs of shoes |
| Accessories and outerwear | Count toward the 33 | Usually left out |
| Length | Three months | No set length: a trip, a week or a style reset |
| Origin | Courtney Carver, 2010 | Popularised on TikTok by creator Rachel Spencer |
The full breakdown, including the outfit maths, is in our guide to the 3-3-3 rule for clothes. If you'd rather keep a small wardrobe all year with no fixed number, that's a capsule wardrobe, and Project 333 is one structured way to try it.
When 33 starts to pinch
The weather turns. Plan for it at the start: one warm layer and one waterproof layer cover most surprises in a temperate season. If you do have to change something, swap one item for one item so the count stays at 33.
You do more laundry. Fewer clothes means smaller, more frequent loads. Tops run out first, so if you have a spare slot, an extra T-shirt is the cheapest fix.
An event comes up. The simplest answer is to keep one occasion piece in your 33 from the start. Borrowing or hiring for a one-off isn't covered by the rules, so decide how you'll treat it before the invitation arrives.
Boredom sets in. Change how you wear things before you change what you wear. Tuck a shirt in, roll the sleeves, wear a shirt open over a T-shirt, or put the jumper over a collar instead of a plain top. Note which pieces you keep skipping, because that list is your best guide to the next season's 33. If you're unsure how big a wardrobe your life really needs outside the challenge, our guide to how many items a capsule wardrobe needs breaks it down by lifestyle.
Questions
What is the 333 rule for wardrobe?
It usually means Project 333, Courtney Carver's challenge of wearing 33 items, including shoes and accessories, for three months while the rest of your clothes stay boxed up. The same name is sometimes used for the 3-3-3 rule, a much smaller challenge built from three tops, three bottoms and three pairs of shoes. Check which one an article means before you start counting.
Who created Project 333?
Courtney Carver, who set out the rules on her blog, Be More with Less, in 2010. She later wrote a book about the challenge, Project 333, published by Tarcher in 2020. Her site still hosts the current rules.
Do shoes and bags count in Project 333?
Yes. Every pair of shoes counts toward the 33, and so do bags, belts, scarves, hats, gloves and sunglasses, which Carver treats as accessories. What doesn't count is underwear, sleepwear, lounge wear worn only at home, workout clothes worn only for exercise, and sentimental jewellery you never take off, such as a wedding ring.
Can you buy clothes during Project 333?
The rules let you replace something that stops fitting or wears out. Beyond that, Carver's guidance is to pause shopping for the three months and ignore sales. If you do replace an item, swap it one for one so you stay at 33. The pause is part of the experiment, because it shows how often you shop out of habit rather than need.
Is 33 items really enough for three months?
For many people it is, because most of us already wear a fraction of what we own. WRAP's 2022 survey of more than 6,000 UK adults found that about a quarter of the clothes in their wardrobes hadn't been worn for at least a year. Eight tops and five bottoms that share a palette already give 40 pairings.
Is there a Project 333 PDF or book?
Courtney Carver's site, Be More with Less, hosts the rules and has published free Project 333 guides. For the full method she wrote a book, Project 333: The Minimalist Fashion Challenge That Proves Less Really Is So Much More, published by Tarcher in 2020. Copies of the rules on other sites vary, so check her site for the current wording.
