Princess Anne wore a belted lavender coat and hat on her way to meet the Queen of the Netherlands in November 1982. Although she balanced the color with a black bag and black shoes, the dress she wore underneath seemed to match her coat.

For accessories, Anne chose a pearl choker and a sculptural gold brooch.

Meghan's double-breasted navy dress blended perfectly with her clutch bag and pointed-toe heels. Her hat also coordinated with the look, which provided a dark canvas for her red poppy pin, a customary piece worn on Remembrance Day.

Meghan chose a caped gown that fell past her ankles, barely revealing the pair of red pumps she wore with the look. She also carried a red clutch in a satin-like material and wore beaded chandelier earrings.
