I’ve never smelled the REAL Good Girl so I can’t attest to how this compares to it but what I do know is that this oil smells SO GOOD!!! I put just a little bit on my wrist yesterday morning and I swear I could still smell it yesterday night. The smell is not too strong, but it’s so enticing and lovely. I normally wear the body spray Bombshell by Victoria Secret but it doesn’t last long. This isn’t nearly as fruity as that one, this one smells a lot more sophisticated while still being flirty. I think I found my signature scent! I have ordered more scents from here in the past and they are always so good. A+I started buying these a few months ago thanks to a recommendation from a friend. I’m obsessed! I love the rollerball applicator so they’re small and easy to take on the go. I keep one in my purse, car and at home. The YSL black opium impression has become my signature scent (one of my best friends told me he knows I’m nearby because he can smell me lol). The only thing I’d say is the packaging couldddd be better, I’ve received a leaky one once but even then there was minimal leakage. Will definitely continue to buy.I bought two different oils. I got the Mons Peris and the Black Opium. The Black Opium isn't anywhere near as close as some reviews lead me to believe. It has more of a vanilla smell than the original. The Mons Paris smells really good, but it doesn't last more than a couple of hours. Overall not bad for $5.I was very pleasantly surprised at how close this smelled to the real Viva La Juicy!I'm a bit of a finicky buyer when it comes to fragrances, and even when I purchase an original cologne at a store, I might return it if it clashes with my body chemistry. I chose the Acqua Di Gio fragrance because 1. I know the original by heart and 2. I really enjoy how it works with my chemistry, so it'd be fool-proof to test it out and if I hated this by-comparison-cheap "impression" or if I loved it.Cost: Absolutely inexpensive. Bottle is roughly the size of my thumb and a couple of "licks" of the roll-on really do a great job. I see it lasting a WHILE, comparing it to maybe a 3.5oz bottle or maybe a bit longer.Product: A bit weird to get used to an oil, rather than a spray, specially since it doesn't have that "IN YOUR F***G FACE" first spritz that only lasts a couple of minutes from the original. That means, you don't get that wonderful "AHHHH" moment when you sniff it out of the bottle. What you get instead about 10 minutes after, is a perfect amount of fragrance and sillage that just won't quit until you shower. I even fell asleep with it on and woke up with a very pleasant aroma on my clothes.Fragrance: One thing I noticed is that the best release of fragrance comes after you've had it on for a bit, and it heats up with your body, otherwise the smell is hardly noticeable. I purchased several impressions at once to skimp on shipping (and I also figured that the more chances I gave it, the higher the chance I'd find at least one I enjoyed). Overall, I was pleasantly surprised with all of them, but still here's a listing of what I thought of each. Acqua Di Gio: It's probably one of the oldest fragrances they have available, so they've had time to perfect it. 5/5. The real deal is 50$ for 3.5oz, so not saving A TON, but out of curiosity I tried it out and I'm happy I did. Abercrombie Fierce: Unlike a lot of people, I'm not annoyed by this fragrance. 5/5. Again, real deal is 50$, so we're still in VERY NICE, but "not a big deal" territory. Paco Rabbane 1 Million: This is where it gets interesting, a $90 bottle can't possibly be replicated by a 7$ knock-off, right? 4.5/5. This one I'd only smelled on a test strip from a magazine, so I've no idea how it would work with my body chemistry. It's spot-on close to the test strip, and I'm extremely happy I didn't buy the original, because I kind of hate it on me. :D I'll pass by the mall and try the original, but besides the initial notes I loved, I think I'm cool not owning this one. Again, that's a personal preference on the original, not the impression. The impression is PERFECT. Tom Ford Oud Wood & Tuscan Leather: $225 each. Too rich for my blood, and also I wouldn't call it a "real" cologne in a sense. It's more like a collection of really nice smells that would go amazing as a layer with other more "average" cologne. Wouldn't know how to rate it, since I haven't even smelled (or even heard of) the real deal, but I thought it'd be a fun experiment, which it was. Once I smell the originals, I'll know: if it's spot-on (which an educated guess tells me it will be) it's a great deal. If it's not spot-on, it's still an enjoyable base to personalize the original colognes I already own.Usage: I would feel totally confident wearing this out, pretty much anywhere. It doesn't have that strange "cheap-cologne" smell. Since it's an oil, I guess I could also put it in unscented body lotion, but that's more for personal usage, since I'm guessing the scent would be perfectly faint. I also see it as a "perfectly safe to waste" fragrance, like when you go to the gym or just day to day activities where you still want to smell great but don't want to spray a $90 bottle for a couple of hrs before you take a shower, which is surprisingly often.So there you have it, in short, buy with confidence and if you're not willing to part with 7$ ea. for the sake of testing one of these out, be my guest and spend however much the one you want costs. I tried them, and I thought they were amazing. With that said, I don't think I'm going to "test" anymore unless I actually like the real deal. (I'm looking at you, Rabbane's 1 Million)Actually very impressed by how close the IMPERIAL, SMW and IRISH TWEED scents are to the REAL deal. I have a few small "tester" bottles of the real CREED scents: EROLFA, IMPERIAL, IRISH TWEED, SILVER MOUNTAIN WATER to name a few. I can't justify spending $300+ on a full bottle because I work a lot and don't really wear any scents except for when I'm not working. So I every once in awhile spend $15 to re-up on a SMALL test bottle if needed. But I compared these scents to the originals, side by side...and MAN ARE THEY UP THERE WITH THE REAL THING! VERY SATISFIED! Will definitely be making future purchases for sure!i got the candle of this smell from a friend and fell in love with the scent. the original cologne is obviously overpriced and this is so close to the original smell that it is my ONLY cologne now. i have never really clicked with any scent of cologne until now and its absolutely worth it...and if you're a harry styles stan reading this-- buy it. its good. its worth it.Was super skeptical at first, I read the reviews and everything. When I got the bottles and tried them it was really great, very easy to apply and the smell lasts a decent amount of time. Even after showering it lingered, guess bc it’s in oil form. Scent projects fairly well, depending on the scent you choose. I got the Creed Aventus (101), Paco Rabanne Invictus (123, one of my favs), and The One (110).Each one has their purpose and when I choose to wear it, highly recommend trying here first before investing in the real bottle. Especially if it’s your first time and you want to try out a scent, this is good way to dive into that new experience.Love this on my wife.Very very long lasting
