When you are shopping for perfume it is important to understand the different types of fragrances available according to their intensity and strength. The ‘parfum’ offers the strongest fragrance and can last for hours. And for the same reason, it is also the most expensive. The ‘eau de parfum’ comes next in strength, followed by the ‘eau de toilette’ and finally the ‘eau de cologne’, which is low in concentration and is usually the least expensive. Now that you know the types of fragrances you can choose from, you can shop according to your budget and how long you want the perfume to last.
