How To Layer Perfumes For A Signature Scent
To know what perfumes you could potentially layer together, you have to examine the notes in each perfume. According to FragranceX, "perfume notes are ingredients that make up a fragrance," such as rose, tobacco, or caramel. They are composed of top notes, which fade after about 15 minutes, and heart notes and base notes, which are what you smell when the perfume dries down.
In order to really know what you want out of a signature scent, you have to play around with the fragrances in your perfume wardrobe and gauge your reaction to them. As a place to start, a common note such as vanilla plays well with most other notes. If you have a scent where you can't really detect the vanilla as much, layer it with another vanilla scent. Perhaps vanilla smells a little boring to you — add a perfume with nutmeg or cinnamon to spice things up a bit.
Layering scents is all about playing things up or down. For scents that are quite heady or strong, add something light that will make it suitable for everyday wear. Many cold weather fragrances often have strong notes like leather or tobacco that can be too overpowering for smaller spaces such as an office. A light floral or aromatic scent will help tone down the scent and blend beautifully with it (via GQ UK.)
