Perfume advice for a soon-to-be 8th grader?

Please help! 10 easy points! I am looking for a long-lasting fragrance that i will enjoy, and that will not be too overpowering for a middle school scene. I have recently looked online, and it looks like the Katy Perry fragrance Purr looks cool, is it good? and I also looked online at the Victoria Secret Bombshell Summer, is it too overpowering? Some stuff on victoriasecret.com looks cool like The Body Mist, and PINK soft and dreamy. But, i really do have so many PINK fragrances, i have alot beauty rushes. 2 can u please suggest something that A. is not too overpowering 2. Not hundreds of dollars C. smeells nice. For this upcoming year, should i set out for a autumn-y scent? Cuz i kinda am lovin the summer-y scents. Also, how do ya feel about the Hollister scents? Please help! i know this is alot of information, but any advice is appreciated!
