Dilum is an eau de toilette. It is one of the most popular fragrance types and tends to have a shorter sillage and lighter scent. On average, it lasts about three to four hours on your skin but can last longer with reapplication or when applied to textiles. Dilum can be purchased at major department stores, but FragranceX is a solid option for buying perfumes and colognes online. FragranceX sells authentic, quality fragrances at discount prices, allowing you to save up to 80% off.
