Let her nose do the choosing!! That sounds like a great idea.
there are heaps of fragrances that I could recommend, but it's better if she chose for herself, with your help, of course
let us know what she ends up picking

Answer:
Hilary Duff''s With Love... surprised me. Much better than I expected. Sweet but not cloying.
Also try Ralph Hot.

Answer:
There's a samples gift at Sephora you can buy. It's this thing where you pay for a fragrance ($35-$40, I think), and they provide ten popular samples, and your sister can pick the one she likes, if you think that would work. Otherwise, if this is more of a sisters-bonding-shopping-trip you're planning, here are a few suggestions (and a few are repeats from others' suggestions):
-DKNY Be Delicious and Be Delicious Red
-Escada Sunset Heat
-Vera Wang Princess
-Calvin Klein Euphoria Blossom
-Givenchy Very Irresistable
-Dior Miss Dior Cherie
-Aquolina Pink Sugar
-Cartier Delices
-Salvatore Ferragamo Incanto Dreams/Charms/Shine (3 diff. versions- all good)
These are the ones that I think fit a teen that are also readily accessible at most department stores. The one exception would be the Cartier, which would be on the pricier side and at more exclusive stores, but I'm sure you know that.
Good luck and have fun!

Answer:
I recommend Chance by Chanel!
