Lady Amelia Windsor makes a stylish appearance at Serpentine Summer Party

Models, actresses and even royalty showed up in style for the Serpentine Summer Party in London on Wednesday. The event, co-hosted by Tommy Hilfiger, wasn't short of some of the best high fashion moments.

Lady Amelia Windsor made a rare, but high-profile, appearance at the event, which was hosted at the Serpentine Gallery. The 20-year-old, who is 36th in line to the throne, looked effortlessly chic in a navy skater dress which featured a halter-neck and cut out detail. Amelia added a bold pop of color with a pair of pink clogs and silver bangles.

The stylish royal kept her makeup natural and styled her hair with two braids tied back off of her face. In June, the blonde beauty raised the fashion stakes during the Service of Thanksgiving for the Queen.
