Thanks to Karin for pointing out this message on the website of niche line Institut Très Bien:
Like a beautiful ballet, Institut Très Bien has ended act one and is in intermission...
We would like to take opportunity to thank all of you who loved the brand [...] We hope to see you soon again.
Hopefully they'll be back. Meantime, if you need to stock up, the scents are marked down at Beautyhabit.
Looking for Cologne a L’Italienne.
