Just in time for the birth of his son, the Duke of Sussex has morphed into full on dad.

On Monday, the beaming prince spoke to media outside of Windsor Castle following the birth of his son, and while he looks insanely happy, he also looks....very dad-like.

The Duke managed to look casual yet put-together despite probably a less-than-ideal night’s sleep in a comfortable half-zip sweater.

Harry is fully rocking the dad look and we couldn’t be happier for the family.

Take a look at how you can rock the stylish “royal dad” look!
