Mary Katrantzou is a master manipulator of digital prints. But this season, she took a more low-fi approach with a collection based on straightforward uniform codes and insignias.

Characterful square-toe styles by Gianvito Rossi were shown in a variety of color and material combos. A blue velvet version with yellow taping was especially smart.
