Ten
'X' marks left on one's body after wearing clothes.
To mark the 10th anniversary of its fashion department, Kingston University held a fashion show at The Design Museum, London in October 2017. Ten students showcased their collections on the runway.  
Marks left on one’s body from wearing clothes in the form of an 'X' was the concept behind this identity.

Brochures with details about the students participating in the show were placed on the seats before the event started.
