I assume that you are speaking of the women's version and not pour Homme. I tend to wear Rive Gauche in warmer weather, but I would not hesitate to wear it year-round. It is a classic floral aldehyde with a cool, silvery, metallic vibe. It is not a summer floral, but rather it is based on classical construction, with aldehydes in the topnotes, a floral heart and woods and vetiver in the base. Some people find it a bit harsh and older formulations are smoother, particularly the vintage parfum, which I definitely wear year-round.
