[Purchased with my own money] Bulgari Omnia Amethyst Eau de Toilette EDT 65ml Perfume

The perfume I'm introducing today is a Bulgari fragrance that is already over 10 years old. I bought it while traveling, and I'm still using it because I cherish it so much. What's truly surprising is that the scent hasn't changed much from when I first got it, even after 10 years. However, the bottle has discolored quite a bit over time. The scent is slightly sweet, yet also feels somewhat sophisticated. I only wear floral perfumes like this for important events. Though, I'm not really sure if it's okay to keep using it for this long.
