I am looking for a new signature scent

Try Byredo perfumes. They are amazing!

I only buy perfume that are cruelty free and use modern non toxic ingredients. My current favourites are Ellis Brooklyn and Where is Elijah. I like to order the discovery sets with mini perfumes so I can try a few at a time. My current favourites are 1. Ellis Brooklyn Myth & Fawn and Where is Elijah Haze & Rebel Rose.

What fragrance notes do you like? it all depends on your preferrence, what works for one person may not suit another.
My faves are:
best floral rose: Lancome Tresor Midnight rose
best floral: dior absaloutley blooming / estee lauder beautiful
best citrus: elle saab
best gourmand: lancome la vie est belle / kayali pistachio yum
best overall: ysl black opium (the original NOT its flankers)

My favourite brand at the moment is Kayali. There are so many scents to choose from in her range. Vanilla Oud from the Oudgasm collection would have the be one of my favourite signature scents

It depends on what you like? Are you a sweet scent lover? Or a musk? I personally love sweet and floral fragrances so could recommend heaps of those?

For a signature scent ones like Estee Lauder Modern Muse, Dior J’Adore, YSL Mon Paris are all gorgeous!

I use the YSL libre such a nic scent feel like it might not be signature tho as many people wear his scent
