Delvaux - Brillant vs Tempete

Hi boppers! Help please! I have had a slight obsession for Delvaux since discovering the L’ Humours Brillant by Pursebop a few months ago… I was in despair that there were no Delvaux stockists near me and that it was sold out in the U.S where I was going to purchase it but joyfully, they opened the first Delvaux boutique in my country this week! Now the dilemma… I have been lusting for the L’ Humour Brillant MM since I first laid my eyes on it and have been told it’s possible to order one, but after seeing a picture of Olivia Palermo with a purple Tempete and furiously looking for photos of it – I think it’s a gorgeous bag. So which one? Pros & cons of both?
