I have both and although they are the same colour, they have two completely different looks about them. The Celine Shadow is a huge statement style, if you're dressed smart or really chic, they can look amazingly high fashion. However, they are very big and in some situations i feel a little silly wearing them. I am a bit over the Celine Shadow in black tortoise colour because i've seen so so many people wearing them. The Celine Cathrine is a new model and also a large pair of sunglasses that i feel are more classic. They are oversized, rectangular but have an edgy cat eye sort of look to them. I absolutely love mine, they look edgy but classic and look great with any outfit. Posh and chic, i really like them. the look great with jeans, smart work outfits and just chilling casually. If you want something that is more classic but still super cool, go with the Cathrine style, but if you want something that stands out as a statement piece that people notice straight away buy the Shadow.
