Want to know the 5 Rs of fashion?
Thank you for reading this post, don't forget to subscribe!
Here they are: Reduce, Reuse, Recycle, Repair, Rewear.
That’s it.
Simple, right?
But wait.
There’s a lot more helpful stuff in this guide.
I’ll show you all the fashion “rules” people talk about.
Like the 3-3-3 rule.
And the 80/20 rule.
Plus what’s actually cool to wear in 2025 and 2026.
No fancy words.
No confusing stuff.
Just simple tips you can use today.
Let’s go.
What Are the 5 Rs of Fashion?
These 5 Rs help you dress better AND help the planet.
1. Reduce
Buy less stuff.
Seriously.
You don’t need 50 shirts.
Pick 10 good ones instead.
2. Reuse
Wear your clothes more.
That dress you wore once?
Wear it again.
Nobody remembers.
3. Recycle
Old clothes can become new things.
Give them to charity.
Or use store drop-off boxes.
H&M and Zara take old clothes.
4. Repair
Broken zipper?
Fix it.
Small hole?
Sew it.
A tailor can make old clothes feel new.
5. Rewear
This is like reuse.
But it’s about mindset.
Stop thinking you can only wear something once.
Kate Middleton wears the same outfits many times.
You can too.
The Ellen MacArthur Foundation says this can cut fashion waste in half.
Pretty cool, right?

What Are the 3 Rs of Fashion?
This is the short version.
Reduce. Reuse. Recycle.
Just three things to remember.
These came from science class.
Remember learning about saving the Earth?
Same idea.
Just for your closet now.
Here’s a real story:
My friend Lisa had 80 dresses.
She wore maybe 10.
She gave away 50.
Now she actually wears what she owns.
She stopped buying random stuff.
She saves about $150 every month.
That’s the 3 Rs working in real life.
The 3-3-3 Rule for Outfits
This rule is perfect for packing.
Here’s how it works:
- 3 bottoms (pants, skirts, shorts)
- 3 tops (shirts, blouses, tees)
- 3 layers (jacket, sweater, cardigan)
That’s 9 pieces.
But you can make 27 different outfits.
Math is cool sometimes.
Try this combo:
Bottoms:
- Blue jeans
- Black pants
- Beige shorts
Tops:
- White t-shirt
- Blue button-down
- Black tank top
Layers:
- Denim jacket
- Gray cardigan
- Light blazer
Mix and match.
Every piece works with every other piece.
Going on a trip?
This is your secret weapon.

The 80/20 Rule in Fashion
Here’s something crazy.
You wear 20% of your clothes 80% of the time.
Think about it.
You probably have that one pair of jeans.
You wear them all the time.
And those 5 other pairs?
They just sit there.
How to fix this:
Write down what you wear for one month.
Notice your favorites.
Get rid of what you never touch.
Buy more of what you actually like.
This idea comes from something called the Pareto Principle.
Business people use it.
But it works for clothes too.
The 60/30/10 Rule for Colors
This rule helps you pick outfit colors.
Here’s the breakdown:
- 60% = Your main color (biggest area)
- 30% = Your second color (medium area)
- 10% = Your pop of color (small area)
Let me show you:
Imagine this outfit:
- Navy blue suit (60% – the big piece)
- White shirt (30% – the medium piece)
- Red pocket square (10% – the small pop)
See how it works?
One color leads.
One color supports.
One color adds fun.
Your outfit looks put together.
Not random.
Not messy.
Interior designers use this rule for rooms.
It works for clothes the same way.

The 5-3-3 Rule for Travel
Going somewhere?
Pack like this:
- 5 pairs of underwear
- 3 complete outfits
- 3 pairs of shoes
That’s it.
You don’t need more.
For shoes, try:
- Sneakers for walking
- Nice flats or loafers
- Sandals or boots (depends on weather)
Three pairs.
Covers everything.
No more overpacking.
No more heavy bags.
The 70/30 Wardrobe Rule
This one is about balance.
- 70% of your closet = basics
- 30% of your closet = fun stuff
Basics are boring but necessary:
- Plain white shirts
- Dark jeans
- Simple sweaters
- Black pants
- Neutral jackets
Fun stuff is exciting:
- Bright colors
- Cool patterns
- Trendy pieces
- Statement jewelry
Basics last for years.
Fun stuff changes with trends.
This mix keeps you stylish without spending too much.
The 10 Item Rule and 7 Item Rule
These rules stop you from buying too much.
10 Item Rule:
Only buy 10 new things each season.
Spring? 10 items max.
Summer? 10 items max.
Fall? 10 items max.
Winter? 10 items max.
This makes you think before you buy.
7 Item Rule:
Have only 7 things in each category.
7 shirts.
7 pants.
7 sweaters.
7 dresses.
Sounds hard.
But it makes getting dressed so easy.
No more staring at your closet for 20 minutes.
The 5 Color Rule
Pick 5 colors for your whole wardrobe.
Everything matches.
Getting dressed takes 2 minutes.
How to pick your 5:
- One dark color (black, navy, or brown)
- One light color (white, cream, or beige)
- One color you love
- One color that goes with #3
- One fun color for sometimes
My friend’s 5 colors:
Black, white, olive green, rust, and camel.
Everything in her closet goes together.
She never has “nothing to wear” days.
The Finger Rule for Dress Length
Schools and offices use this rule.
Stand up straight.
Put your arms down at your sides.
Your skirt or shorts should reach your fingertips.
That’s it.
If it’s shorter?
Might be too short for some places.
If it’s longer?
Totally fine.
Easy way to check if something is appropriate.
The 10cm Rule for Heels
Heels over 10cm (about 4 inches) hurt your feet.
Stay under 10cm for comfort.
You can still walk normally.
Your feet won’t hurt at the end of the day.
Foot doctors recommend this for everyday shoes.
Save the super high heels for special times.
The 90/20 Rule
If you haven’t worn something in 20 times of getting dressed, let it go.
Think about it.
You got dressed 20 times.
That shirt stayed in the closet every single time.
It’s not working for you.
Give it to someone who will wear it.
The 20 Year Rule
Fashion comes back every 20 years.
What your mom wore?
It’s probably cool again.
90s fashion came back around 2015.
2000s fashion came back around 2020.
2005-2010 styles are coming soon.
So keep your classic pieces.
They’ll be trendy again.
What Not to Wear at 60 (Or Any Age)
Here’s the truth.
There are no age rules for clothes.
Wear what makes you happy.
But some tips help:
Fit matters most.
Clothes should skim your body.
Not too tight.
Not too baggy.
Good fabric looks better.
It hangs nicely.
It feels nice.
Skip things that:
- Feel uncomfortable
- Need constant fixing
- Make you feel old
The goal?
Feel good.
Look confident.
That’s it.
