Princess Beatrice had a rough go at it back in 2011, when her squiggly Philip Treacy wedding hat put her on the fashion map -- "worst hat ever," was it?

Maybe. But as a major royal (she's William and Harry's first cousin, granddaughter to Queen Elizabeth II and even Kate has to curtsy to her), Princess Beatrice has worn her fair share of toppers and there are inevitably some questionable picks in the mix. (The Royal Wedding wasn't her first time at the giant hat rodeo...)

But, as Bea has proven this year, she's also in possession of some impeccable taste. Like her flawless red Elie Saab frock or her perfect hair, there are awesome fascinators rounding out the royal's collection.

And that should be enough to forgive her egregious wedding day sin, right?

Right. So in honor of Princess Beatrice's 24th birthday today, here's a look back at the royal's best and worst hats. Which are your favorites?
