At first I was skeptical of buying imagine bloom dust because of the price for the amount that you get, but as soon as I Received the product I was totally shocked. I own both the real imagination and the interpretation by IBS. Let me just say you have to have tons of experience with fragrances to smell them apart. There is almost no noticeable difference between the 2 and I would say they last equally long. Not only was the product itself great, but the packaging and presentation was also really good. You can just tell that they actually care about each customer and take their time with each order. Definitely worth the purchase.
