Duchess Kate Middleton stuns in red Jenny Packham just hours after giving birth

Duchess Kate has stepped out to introduce her newest bundle of joy to the world, a baby boy weighing in at 8lbs 7ozs. The baby will share the title of Prince of Cambridge alongside big brother George and is currently fifth in line to the throne.

Despite giving birth just hours before, Kate looked every bit radiant as she left the Lindo Wing to bring the new prince home. The 36-year-old mom chose a custom fire red gown by her go-to designer Jenny Packham, a favorite of the royal before and during all of her three pregnancies.

The long-sleeved dress, which included a detailed peter pan collar, went perfectly with the Duchess' nude stilettos and her signature flawless blowout.

Though Duchess Kate also sported a Jenny Packham dress for the arrival of her two older children, today's outfit is a much bolder look than before. For Charlotte's birth in 2015, Kate sported a long-sleeved floral yellow gown, while she went for pale blue gown with polka dots for George.

Many have also noticed that the red choice can be seen as a sweet tribute to Princess Diana, who wore a near-identical dress to introduce Prince Harry to the world in 1984. Similarly, the dress Kate wore when introducing Prince George resembled the blue dress Princess Di sported with Prince William.
