This week's best royal style: Kate Middleton, Queen Letizia, Queen Maxima

With the birth of Princess Charlotte this week, all eyes were on what Kate Middleton would wear to show off her new little bundle of joy. The Duchess once again turned to designer Jenny Packham — the designer behind her polka-dot blue dress at Prince George's debut — this time choosing a chic cream and yellow bespoke creation, accessorizing with a pair of nude Jimmy Choo pumps.

Though the Queen wouldn't meet the new little Princess until days later, she did show her excitement for her new great grandchild while visiting Richmond Castle in North Yorkshire. She acknowledged the birth by wearing pink during her day of engagements, sporting a vibrant fuchsia coat and matching hat.

Aside from the British royals, Queen Mathilde of Belgium opted for a baby blue ensemble as she and daughter Princess Elisabeth headed to the naval base of Zeebrugge to name the patrol boat P902 Pollux. She looked elegant as always in a pale blue pleated skirt and jacket and completed her look with a matching hat, nude patent stilettos and a pair of pearl earrings. Her daughter was just as fashionable in a blue printed dress with a matching headband and cream-colored coat.
