Think you can't spot a princess from a mile away? Think again.

There are plenty of ways to pick out a royal, whether she be a princess, queen or duchess, simply by taking one look at her outfit. Yup, there's an unofficial criteria to getting dressed each morning that separates us plebes from princesses -- in fact, some of you non-royals may just fall into many of these categories, too. Herewith, seven ways to tell if you're actually a princess.*

1. When you wear something, everyone wants it, too.

2. You rock nude pantyhose.

Princess Mary of Denmark and Queen Mathilde of Belgium

3. They're not "hats" -- they're "fascinators."

Princesses Beatrice and Eugenie of York

4. You don't go to the salon for blowouts, the blowouts come to you.

Kate Middleton (who has a special royal tour hairdresser ) and Princess Letizia of Spain

5. Your closet is filled with matchy-matchy monochromatic outfits -- hey, solids are classic.

6. Everyone's in shock when you wear jeans.

Princess Madeleine of Sweden (who's a denim aficionado ) and Charlotte Casiraghi of Monaco

7. Your haircuts are major.

Kate Middleton (who stopped the presses with her "bangs" ) and Princess Charlene of Monaco (who gave us the most surprising princess haircut ever )

*We're using the term "princess" to include queens who used to be princesses, too (though it's worth noting that Kate Middleton did, in fact, list her occupation as "princess" on Prince George's birth certificate ).

CORRECTION: Language has been amended to indicate that "princess" is listed as the duchess of Cambridge's occupation on her son's birth certificate and not as her official title.
