I received this perfume as a gift when I was just 13 years old.&nbsp;<br><br>As a teenager, this was the perfect perfume. Fresh, subtle, but still special.&nbsp;<br><br>This was a great product for daily use, but for special occasions, I would recommend something more unique and intoxicating.

This is truly unisex as it smells great no matter who is wearing it. I like to wear this in a sporty situation like a baseball game or a trip to the beach. Its light fragrance is a go anywhere type of scent. I would recommend this fragrance to a young person not yet sure of their signature scent.

One of the first since I remembered buying years ago. For me, this is a clean, crisp, fresh classic that can be used by both men and women. although it reminds me of the 90s I feel like it's a scent that just doesn't go out of style. I'm so glad they still make this product!

I know CK One is a bit of a modern classic now, to the point of being instantly recognizable by many who experienced middle or high school around the time it came out. However, this scent holds up as a solid, day-to-day fragrance that is extremely office-friendly and subtle. The bergamot is fresh and unisex, and this feels like a precursor to high-end unisex scents like Le Labo Bergamote 22.

Clean and gorgeous. This is my favorite to throw on if I know I'm going to have to spend time outside, probably sweating, around people. The scent isn't too overpowering and leave just a whisper of scent. It's really a gorgeous little concoction and it will be in my rotation until something even better comes along from Calvin Klein

It's been in my staple product pile for a very long time. I love #ckone it's a very clean scent that is not overpowering. I cannot really think of anything I'd change. It lasts all night at work for me. I love that it's a glass bottle. I actually carry one in my purse but never really need touchup

This is my go to fragrance when I can’t decide. It is light enough for the office but long lasting for the work day. The bottle is plainly pretty. I would only recommend that it come in a roller ball applicator. I would definitely buy it again and again! 

Calvin Klein One was ALL the rage by the time I was finishing up junior high in the early-mid 90s.   I am pretty sure that this is the first perfume in which I spent my own money.   I just remember it smelling so grown up and wearing it out to the mall and to go to the movies.  While I haven’t worn it in years and wouldn’t be able to give an honest review based on being a 37-year-old adult, I do remember this perfume making me feel as though I had finally entered the world of being a teen while I haven’t worn it in years and wouldn’t be able to give an honest review based on being a 37-year-old adult, I do remember this perfume making me feel as though I had finally entered the world of being a teenager on the verge of growing up.   I was a bit awkward in my elementary and junior high years, and having this perfume on me gave me a sense of finally belonging and feeling a bit womanly and accepted. 

This smells so so good! It's definitely a pricier scent but it does have such a great lasting power and doesn't smell like harsh chemicals. It's kinda got that 'generic men's scent' to it so be wary if using with a strong deodorant, sometimes the mix is not great.

I love “one” by Calvin Klein! Me and my girlfriend always use it and it’s a great scent that we both can use! It’s very long lasting and is a clean and fresh scent! It’s a great price for how much product you get. I 100% recommend this product to both women and men!
