Ck one used to kinda be my jam for a very specific moment in time when it first came out. Which is kinda funny because it's really not the kind of scent I would think I'd like, but I really did at the time. (I haven't smelled the original in a long time, so maybe I still would. Who knows?) So when I got the chance to try ck one Summer (the English major in me really balks at the non-capitalization of the actual name, but I will abide by Calvin's wishes!) I jumped at the chance to see what the summer version was all about. And... I kinda think I like it more than the original (from what I remember). The top note in it is lime mojito (I know!), the middle note is sweet guava, and the base note is cedar wood. It's kind of like a fruity, fresh scent - not heavy or floral - and it's weird how I really could see either a man or a woman wearing it. It definitely reminds me of the warm weather and the beach and a tropical location. I think I'd wear this on vacation or to brunch on the weekends. Also, now I reallllllllly want a mojito. Someone make that happen!
