When the royals have a fancy affair to attend, you can bet there will be at least one tiara involved. And while Princess Sofia of Sweden may be new to her title [1], she has already mastered the art of royal dressing, headgear included. Sofia attended last night's Nobel Prize Banquet in Stockholm dressed in a stunning navy ballgown complete with a sheer top with floral appliques. Sofia and husband Prince Carl Philip [2] announced that they are expecting their first child this Spring, but Sofia's baby bump was under wraps in this full-skirted creation.

Sure, the gown was a style statement on its own, but no formal royal look would be complete without a shower of elegant jewels [3]. Sofia donned the dazzling diamond and emerald tiara that was made for her wedding day and even had earrings to match. Sofia also sported a radiant brooch on the sash she wore slung over one shoulder. Read on to see her stunning look from last night, including plenty of swoon-worthy sparkle.
