Jazz dance, or modern dance it
I think modern dance is better than jazz dance, of course, jazz modern dance looks good, I think ah. Of course jazz is more on the sexy side.
You're kind of a small body, I think it's better to dance cute. The same kind of dance is not some choreographed very hot and some very lively, that's for sure, and the same dance, everyone dances out of the feeling is not the same.
I think girls your age are better suited for Korean dance, recommend a few ah:
TIARA's bo peep bo peep (tiger dance)
Kara's mr (pp dance) and wanna
wonder girls' tell me and so hot, nobody (not too recommended, too many people dancing)
Wonder girls' tell me and so hot, nobody (not too recommended, too many people dancing)
Girls Generation's oh!(lesbian dance) and gee(this one is also danced by a lot of people)
after school's diva
beg's sign(fan dance)
