In 1994, club maven Sylvie launched the first Thanx God boutique, dedicated to designer vintage clothing, on Rue Greneta. The house nights she ran in parallel – at l’Elysée Montmartre or the Salle Wagram, amongst other mythic clubs – became a favoured rendez-vous for the queer and fashion sets. In 2008, she and her DJ and sound engineer partner Amnaye relaunched the shop in the 10th arrondissement, where it continues to be a beacon for devoted followers of fashion everywhere. In 2018, Sylvie launched her own line of luxury essentials, Maison Chateigner.
