I'm going to go out a limb here and say that almost any suede shoe is worthy of a 'Not So Casual Friday' mention. I mean, it's probably the most high-maintenance shoe material going, and therefore best saved for special occasions and evenings when you're going to little except walk into a restaurant and sit.

So wet-look suede with diamanté and silver studs by Jimmy Choo is about as not-casual as you can get, wouldn't you agree? These heels are mighty pretty and, joy of joys, they look even prettier actually on the feet (check out the model picture on Net-a-Porter). Not-casual comes at a price though and these ones are marked at £695.
