My mom used to wear the late 70s era Opium in the 80s before all the changes in the scent profile. When I surprised her with this she loved it and hasn't stopped wearing it currently she has one more backup bottle until the website we purchase fragrances from restocks. You can't beat the price of this.
Scent wise of course cinnamon is the star of the show, coca cola is seriously in this. Without writing 2-3 pages it turns into this old library like scent briefly that one woman on Youtube said which I can't unsee. You don't smell it in the air much after the first few moments. Just up close. There's some earthiness to this as well from the patchouli and possibly oak moss. However even when you first spray it underneath the library scent there's this refined and elegant spices that come off as warm and uplifting.
What surprised us is how many complements she received wearing this. Even from complete strangers. Attached is a photo of the bottle she just started.
