Proenza Schouler Ps1 or Cambridge Satchel!1

So I've been browsing the web because I was looking at Jack and Lazurus's beautiful Ps1's because I wanted to buy another one. Hmmm. but I came across this European bag the Carolina from fashion squad was wearing and its call Cambridge Satchel. The vibrant colour and its shape reminded me of the Ps1. What do you guys think. For me I have to be faithful to my Parson's alumi Jack and Lazurus! I love the Ps1. What are your thoughts!
