eau de toilette and eu de perfume are the same, eau de perfume costs more and you only need a little dab because the smell is stronger, the eau de toilette is cheaper and you need more sprays cos the smell doesn't last long.
Eau de toilette/cologne is less concentrated. Lighter fragrance and smell may not last as long.


Eau de parfume has more concentrated perfume fragrance so smell lasts longer
