Honestly, can you have too many? Guerlain’s latest fragrance, La Petite Robe Noir, was inspired by the elegance and timelessness of everyone’s favorite go-to dress and has a light, flirty scent that is equally versatile. The bottle is a replica of the Guerlian’s L’Heure Bleue and Mitsouko fragrances and has a sweet upside-down heart-shape stopper. The chic little black dress on the bottle was designed by Serge Manseau. $57, shower gel; $58, body milk; $64 to $115, perfume in three sizes; available at Sephora stores and sephora.com
