Saw this at the mall today & took a whiff. With my sister at my side I had her spray it on her wrist.
It wasn't unpleasant - very cotton candy'ish, being similar to the sweetness of Nicki Minaj's Pink Friday however not as cloying. The green apple was a nice touch with the grapefruit keeping it more fresh and less heavy.
After the first 30 minutes it becomes less "thick sweet" and more fruity, powdery fresh. In a hot summer scenario I could see this being a night scent or on days that are below 80 degrees plus. I do notice a synthetic vibe however not enough to annoy or cause frustration. All in all my sister really enjoyed it and was very close to purchasing. Not bad... But as a few of you have mentioned - This was created for 1 Direction's groupies' age group, understandably.
