What is this brand called?

The brand or maybe designer is two words, the first one starts with a C and the second one starts with a K. It's not Calvin Klein. I saw this girl with a blue bag with flowers on it (it looked like it was kind of plastic, it was kind of shiny too and it was really plain, just the handle part which was from the same material as the rest of the bag and the bag) and I was trying to look at the designer, but I could only see the C and the K. If you know what I'm talking about, please help me.
