Only you perfume collection No. 809 30ml

The difference between

Eau de toilette & Eau de parfum: 

Eau de toilettes have a relatively light spray composition—5% to 15%—of pure

perfume essence dissolved in alcohol. Expect these to last for about 3 hours.

Eau de parfum are second only to their cousin perfume in strength. These contain

between 15% and 20% pure perfume essence and can last up to 8 hours.
