Keep it, I think it looks great on you, not too nude at all. I love it with your jeans and grey t-shirt, and would wear it with practically the same outfit.
Its very different from your Noe, so I think they compliment each other.
I am trying to track down the Pink Beige with the shoulder strap aswell as the top handles.
Love your little Agenda too, I have the Pochette in the same design!
The bag is gorgeous -I have another question how are the light coloured chloe leathers for colour transfer thats always my worry?
