I've covered royal fashion for a decade now, so you can bet I've noticed some recurring themes when it comes to the outfits royals wear. While everyone has a unique interpretation of royal dress codes, there are still a handful of rules all royals seem to abide by, whether on purpose or not. 

For starters, royals avoid wearing denim cutoffs, as the laidback staple is typically too casual for them to be photographed in. Instead, the Princess of Wales and the Queen of Spain both opt for tailored shorts, which are still relaxed but slightly more elevated than denim shorts. Scroll down to see four things royals don't wear and what they wear instead.

Associate Director, Fashion News

Erin got her start as a Who What Wear intern over 13 years ago—back when the site only published a single story per day. (Who What Wear has since increased that number twentyfold.) She graduated magna cum laude from USC, which is how she ended up moving to Los Angeles from her hometown of San Diego. In college, she also interned at Refinery29, where she was promoted to editorial assistant and then assistant editor. After nearly three years at R29, she came back to WWW in 2016, where she currently holds the title of Associate Director of Fashion News (as well as the unofficial title of resident royal expert—in case you haven't noticed her numerous Meghan Markle and Kate Middleton stories). She spends her days trying to incorporate her idols, Anna Wintour and Roger Federer, into as many stories as possible. Outside of work, she loves tennis, classic rock, traveling, and smothering her dog with affection.
