'Jumpsuits are welcome' at Royal Ascot 2017 -- so we picked a few for Duchess Kate

Three words that are music to our ears: "Jumpsuits are welcome."

That's what the Style Guide for the Royal Ascot 2017 reads -- and it's a big change that's "new for 2017." According to the Mirror, "The last time Ascot [organizers] made such a significant [change] was back in 1971 when the trouser suit was incorporated into the dress code."

Though the piece could be considered casual among the various fancy attire worn at the Royal Ascot, with the rise in popularity of the pantsuit (thanks, Hil) and the jumpsuit (they're everywhere), we're not all that surprised this alteration to protocol was made.

With that said, the inclusion of the jumpsuit doesn't come without its own regulations. As the guide reads, "Jumpsuits are welcome. They should be of full-length to the ankle, with regulations matching that for dresses." Furthermore, "Straps must be of one inch or greater and strapless, off the shoulder, halter neck and spaghetti strap styles are not permitted."

The five-day event kicked off on Tuesday, and Duchess Kate has already turned heads -- and not just for her gorgeous lace dress by her go-to designer, Alexander McQueen. Instead, everyone's talking about the moment when Sophie, Countess of Wessex, nearly fell on the Duchess of Cambridge while climbing into a carriage. The best part? The two hilariously laughed it off -- and the photos will make your day.

And though Kate looks lovely in her lace number, in light of the dress code change, we found a few stunning jumpsuits that we think would look gorgeous on her:
