We’ll start with Départment Féminin, best edit of any luxury multimarque anywhere, and located in Toulouse. Luckily for us, they also have a website. I’ve talked about the founder Carole Benazet’s elegant home here before, as well as her store.
To cut to the chase, I believe that you, dear imaginary luxury fiend, could probably use some gloves.

You should also really have a Balenciaga City bag. Clémence Poésy looks so darling with hers – when is that ever not enough of a reason?

And yet, the Celine Classic bag is so perfectly subtle, and you can't be a rockstar everyday can you?

Warm up that credit card – I think you might need both of them.
And to top things off, so to speak, how about a Sarti scarf in khaki (or gray like Garance's)? The way the cashmere folds and billows around the neck – you’ll want to write a thank you letter to the nice goats who provided their woolly down!
