Kate Middleton Halloween Costumes For the Royal-Obsessed

Keep it casual in a polo shirt, jeans, and some sneakers for Kate's sporty look.

Deck yourself out in some ski goggles, a puffy white jacket, and some red ski pants and you'll be dressed to hit the slopes, just like Kate.

Throw on a sparkly blue gown to look like Kate did at a Bollywood charity gala during her tour of India in 2016.

Throw on some shades and a bright yellow dress and you're all set.

Nothing says "Kate Middleton" quite like a simple, tailored dress and a fascinator in the same color.

Wearing a ladylike, classic red coat and hat, you'll be good to go for a royal-tour inspired outfit. (Bonus points for carrying a doll or baby.)

Channel Kate's glamorous evening look with a long, ivory dress.

Keep it simple by copying Kate's favorite on-the-go style: a striped shirt, jeans, boat shoes, and sunglasses.

After Prince George was born, Kate and William introduced their son to the public with the hospital photo op seen around the world. (And then, of course, they had a similar moment with Charlotte!) A blue polka-dot dress, nude heels, and a baby doll are all you need to channel Kate's memorable first-time-mom moment.

Since Will and Kate welcomed their second child, Princess Charlotte, this year, it's the perfect time to channel pregnant Kate! Pair a ladylike pastel dress or coat with a fancy hat, and then add a baby bump to turn it into maternitywear.

Layer a white, long-sleeved lace shirt beneath a strapless white dress to channel Kate's wedding-day look. And don't forget the tiara!

Who could forget that gorgeous blue wrap dress Kate Middleton wore when she and Prince William announced their engagement? Or, ahem, that stunning blue sapphire ring passed down from Princess Diana?
