These Ventura flats by Rocket Dog are casual, girlie and simple, but they have neat piping and a pretty rosette to make them stand out from your average casual ballet pump. They look a bit like trainers, but not quite. Sort of like a hybrid between a ballerina pump and Vans.
They make cute and comfy shoes to slip on when you’re going somewhere that doesn’t quite require dressing up, but they’ll still look more fashionable than just plain black flats.
You can get them from Schuh.
