This was all I would wear when I was like 15. I repurchased the watermelon scent about 20 times and would spray it about a billion times a day (probably not too good for my lungs, but oh well).
These are definitely aimed at younger girls, I'd say 11-16. If you're a grown woman, you probably couldn't get away with smelling like pure candy and sugar, but if that's what you're into, go for it!
I actually had a bit of an old spray left (the watermelon one, of course) and I used it last week as a bit of a last resort. To my surprise, my boyfriend loved it. I think he liked it better than half the purfumes I have. Even though I probably wouldn't start wearing it every day, it just goes to show that you could probably get away with wearing this in your 20s and people (probably) won't think you're crazy.
I personally wouldnt call this a deodorant... id call it a spray... deodorants are ment to keep you fresh and this only makes you smell nice... i dont use it anymore cause if you end up getting hot and sweaty it doesnt do what deodorants do and keep you fresh.... i think as a deodorant it would be more for younger girls but for older woman i think a spray...
