Kate Middleton honours Princess Diana in new Instagram portrait

In the photo, Kate can be seen looking away from the camera while flashing a warm smile, while donning a bright red sweater over a white button-down that has a pie-crust collar.

Diana was spotted very frequently wearing the playful piece in the '80s and '90s and even popularised the style.

The People's Princess was known to accessorise the collars with delicate ribbons or pair them with overcoats and blazers.
