Everyone carries a private list of styling rules, from never blue with black to always one gold thing. Phia lets you write up to ten of them inside Style analysis, and keeps them in mind when it suggests outfits from your closet. Here is how to write good ones and which old rules deserve to retire.
Personal Styling Rules: How to Write Yours and Use Them
Rules we inherited
No white after Labor Day is the most famous styling rule in America, and it was never really about style. It grew out of late nineteenth and early twentieth century etiquette, when the well-off wore light summer whites on holiday and packed them away when they returned to the city in September. Labor Day became a federal holiday in 1894, and the rule hardened into a social marker that lasted well into the last century.
Confession #1: I followed it until my twenties without ever asking why. Most of us carry a list like that. Never navy with black. No brown shoes after six. Never more than one statement piece. Some were passed down by mothers, some by magazines, some by a single unflattering photo.
The interesting thing is that everyone's list is different, and almost nobody has written theirs down. Which is a shame, because a written set of styling rules is one of the clearest descriptions of personal taste there is. What you refuse says as much about you as what you love.
Ten rules, in your own words
Inside Phia's Style analysis tab, under your top colors, vibes and brands, there is a section called Styling rules. You can add up to ten rules you swear by, in your own words. I never wear blue with black. I hate green and red together. Always a belt with high-waisted trousers. Gold or silver, never both.
There is no form to fill in and no list to pick from. You just write the rule the way you would say it to a friend, which makes it oddly satisfying, like finally putting a long-held opinion on the record.
The rules live next to a written description of your style that Phia builds from your digital closet. That closet fills itself from Gmail, from your camera roll and from checkouts with the Phia extension, so by the time you write your rules, Phia already has a good idea of what you own. The rules tell it how you like to put it together.
How to write a rule that helps
The best styling rules are specific and true. I never wear blue with black is a good rule, because Phia can apply it and because you actually believe it. Dress better is not a rule, it is a resolution.
A practical test: for every rule you write, think of a time you broke it and hated the result. If you can, keep it. If you cannot, it is probably a rule you absorbed rather than one you hold, and it will only make Phia's suggestions narrower than your real taste.
What I would skip: rules about what you wish you wore. If your closet is half sneakers, never sneakers with a dress will fight the clothes you own. Write the rules for the closet you have. And leave room. Ten is the limit for a reason, because a style with fifty rules is a uniform, not a point of view.
Rules that shape your outfits
Once your rules are in, Phia keeps them in mind when it suggests outfits from your closet. In the Outfits tab, Suggested outfits for you appear at the top and a tap saves any you like. Style from one item builds a full look around a single piece. Generate outfit starts from scratch and builds several complete outfits from what you own.
In the For you tab, Styled by Phia sends a new outfit idea every day once you have added five tops and five bottoms, and if you add your city, the outfit of the day can factor in your local weather.
This is where styling rules stop being a list and start doing work. Without them, an outfit generator will happily pair your navy coat with your black trousers. With them, it knows you would rather not. I wrote more about the outfit side in Choosing an Outfit Planner App You Will Actually Open.
The rules I broke on purpose
Writing my rules down made me notice which ones I had already outgrown. Never brown with black went the moment I saw how much of my closet was exactly that. No white after Labor Day lasted about a minute. The rules that survived were the ones about color clashes I genuinely cannot live with, and those are the ones Phia now works around.
I revisit the list at the start of each season, the way you might reread an old diary. It is a small, honest record of how your taste is moving.
If you want to write your own, download the free Phia app, connect Gmail so the closet can fill, then open Style analysis and scroll to Styling rules. On a laptop, the Chrome extension brings Phia's price comparison across more than 220,000 sites to any product page. Wear white in October if you like. Just write down what you will not do.
