We often wonder how certain celebrities and royals manage to find a winning look every time they step out. On one hand, they definitely have help: they're pals with designers, work with talented stylists, and have picked up plenty of tricks. But on the other, they've also developed specific aesthetics, and tend to stick to outfit formulas. For example, Princess Diana was a big fan of the color red.

Looking through some of her best and most memorable outfits, this color pops up over and again. Princess Diana frequently wore red gowns to big events, accessorized with red bags and hats, and was occasionally captured out and about in casual red items, such as sweaters and loose pants.

To be quite honest, we hadn't realized just how much Diana loved this bright, bold hue - which is also a known power color - until we looked back. Check out 20 times she convinced us that it deserves a spot in any and all wardrobes.

Some of Princess Diana’s Best Outfits Included the Color Red

Gowns, suits, sweaters - you name it, she had it in this vibrant shade.
