Without us knowing, we natural gravitate toward scents that mesh well with our natural body chemistry. One scent can smell entirely different from one person to the next. Fragrances are categorized into 4 categories as you will see below and within those family groups you will find sub families broken down a little bit more to help you better understand the notes.
To also help, I added some fragrances that can be found throughout the site and may be found in the Monthly Scent Box.
