Who knew someone so little could upstage one of the world's style icons, aka Duchess of Cambridge Kate Middleton, aka his mom? However, at just nine months old, that's exactly what His Royal Highness Prince George of Cambridge did during the three-week-long royal tour of New Zealand and Australia.

Since his tour debut on April 7 in New Zealand wearing a cream sweater, pants, and Early Days pre-walker shoes, the tiny royal sealed his spot as a bona fide trendsetter in baby fashion.
Take a look at more of his best outfits from the royals' tour.
For his first official royal engagement on April 9 in Wellington, New Zealand, George wore the Sailboat Smocked Dungarees by Rachel Riley over the Milo Body onesie by Chelsea Clothing Co. Just as his mum has the "Kate Effect," the royal baby has also inspired the "George Effect." The $129 overalls sold out after his appearance, and now there is an 8-week-long wait-list for purchase.

George gave a nod to the harbor city of Sydney for their arrival on April 16 with a sailboat smocked romper by Annafie. The now-named "Prince George Romper" is available for purchase (with a June shipping date) for about $100, or 60 pounds.
To meet his namesake bilby at the Taronga Zoo in Sydney on April 20, Prince George wore a striped polo and navy pocket shorts. Both Rachel Riley pieces are still available online for $69 and $89, respectively.

For their final appearance of the tour, Prince George seemed to channel his mother's red tour debut outfit. As the royal family boarded the plane, George wiggled goodbye to Oz in a red sweater and shorts.
