Think you know everything there is to know about fashion? We're betting that even the most hard-core fashionistas won't know some of this style trivia 琐事. Prepare to be amazed (and a little shocked).

　　1、Queen Elizabeth I is responsible for the whole British hat thing.

　　If you're wondering why our stylish friends across the pond seem to top off every event with a hat, you can stop wondering. The British tradition of wearing hats to most formal occasions is often credited to Queen Elizabeth I. In 1571, during her rule, a law was created that mandated(命令) that anyone over the age of seven must wear a hat on Sundays. And while the law is long gone, there are some events that still seem to have an unofficial hat dress code, including horse races, garden parties and weddings—like Kate Middleton and Prince William's, if and when they ever decide to get hitched.

　　2、New York City: birthplace of Calvin Klein, Ralph Lauren and…the thong.

　　While the loincloth 缠腰布has popped up in history everywhere from medieval times to ancient Egypt, the modern G-string is rumored to have been born in New York City, near the end of the Depression. In 1939, New York City mayor Fiorello LaGuardia ordered the city's exotic dancers to be more covered up in honor of the World's Fair. And, voila, the thong—as well as the unfortunate whale tail—was born.

　　3、Your shoe addiction is nothing compared with Imelda Marcos'.

　　When the former First Lady of the Philippines Imelda Marcos and her husband were kicked out of their palace and exiled in 1986, she had to say goodbye to 2,700 pairs of pumps 轻舞鞋, stilettos细高跟鞋 and slingbacks露跟女鞋. That's 5,400 shoes. But before you get too jealous, remember: This was a time before all the designer booties 战利品and sky-high wedges we've been drooling 垂涎over recently.

　　4、Marilyn Monroe had a pricey birthday suit.

　　Diamonds might be a girl's best friend, but rhinestones 水晶石aren't so bad either. Especially when 6,000 of them adorn a flesh-color gown worn by Marilyn Monroe. The dress that the original blond bombshell wore while delivering JFK's birthday serenade at Madison Square Garden in 1962 fetched more than $1.26 million at a Christie's auction in 1999.

　　5、Witch of the West wasn't the only one who had a thing for Dorothy's shoes.

　　In 2005, someone swiped 猛打one of the original pairs of ruby slippers worn by Judy Garland in The Wizard of Oz from a Minnesota museum. The pricey shoes—with an estimated value of somewhere between $660,000 and $1 million—have yet to be recovered, though it's doubtful anyone could get away with wearing them without attracting attention. (Unless of course she planned to debut the stolen shoes at Wicked.)

　　6、Marie Antoinette wasn't into showing skin.

　　While Kirsten Dunst played a flirty Marie Antoinette—complete with bedroom eyes and low-cut necklines—the real teen queen was so modest that she always wore a flannel 法兰绒gown buttoned up to her neck while bathing! To be fair, though, if you had a slew of staff huddled around the tub, you'd probably want to stay under wraps too.

　　7、The wedding dress that keeps on going, and going and going…

　　No runaway bride here: A Chinese woman recently broke the record for the longest wedding train. The 1.2-mile-long train took 200 guests a whopping three hours to unroll. And in case the thing wasn't obvious enough on its own, it was adorned with 9,999 silk red roses.

　　8、Fashion shows can be squeezed into one day.

　　As many of you style-ophiles know, New York Fashion Week boasts more than 75 shows in a span of just eight days. And while there's one (sometimes two) scheduled to take place every hour from 9 A.M. to 9 P.M., the fashion show itself lasts only about 15 minutes max. That means that Fashion Week's total models-on-the-catwalk time tallies up to about 19 hours. Now, if only that fashion marathon were on pay-per-view.
