Ever wonder why some people always look effortlessly stylish, even in jeans and a T-shirt? The secret might be the viral “Rule of 7” fashion hack making rounds on TikTok.

Popularized by creators like @sreyahalder_ and @digitaltaylor, this rule turns outfit-building into a simple math game. Every clothing item or accessory gets a score, one point for basics (like plain tees, jeans, or hoops) and two points for statement pieces (like printed jackets, chunky shoes, or bold bags). Combine these elements until your outfit totals seven points, and voilà, an instantly balanced, elevated look.

For example, a white tee (1), brown pants (1), unique shoes (2), a fuzzy coat (2), and gold hoops (1) make seven, the sweet spot between simple and chic. Add more and it might look overdone; less, and the outfit may feel unfinished.

Creators even apply it to workwear and brunch outfits, layering accessories, scarves, or blazers to hit that magic number.

While it’s not a strict rule, the “Rule of 7” helps anyone even fashion minimalists, curate looks that feel intentional, stylish, and put-together without overthinking it.
