So it turns out, Kate Middleton is quite the beauty guru! The Duchess of Cambridge has had her busiest week in a while, but what fans noticed about her appearances on Monday, July 9 for Prince Louis' christening and on Tuesday, July 10 for a military service was that she sported the same exact bun both days. So, what's her secret? Apparently a hairnet!

If you look very closely at the photos of Kate's updo from the second event, you will see a very subtle hairnet wrapped around the low bun. The hair accessory — which costs only $2 — is so thin and matches her hair color so well that you can barely see it. What a genius way to re-wear your hair the next day!

Kate's hair always looks fabulous — and so do the outfits she pairs her perfect strands with. For her third royal baby's special day, she paired the bun with a large beige headband adorned with a large flower on it that paired perfectly with her matching Alexander McQueen. For the military service with her husband, Prince William, and Meghan Markle and Prince Harry, she wore a baby blue dress with a matching hat, also adorned with white flowers.

Whenever Kate sports a chignon, however, it's very tight, unlike Meghan, who often wears a messy bun when attending her public appearances.

Fans have always noticed that Meghan often breaks royal protocol with her hairstyle choices unlike Kate, but they're always wondering why. And apparently, it's because Queen Elizabeth is being more lenient nowadays. "It’s her age," shared Ingrid Seward, author of My Husband & I. "She is easier-going. It’s refreshing that [the royal family] is prepared to bend a bit."
