How to look more attractive to guys?

I am a 17 year old asian still in high school suffering a little confidence bust. It's been 2 years in my senior high school and I have only had 2 guys like me and 1 date. How do I even make myself look a little more attractive to the opposite sex?I have always been pretty comfortable in my own skin, but I;ve been starting to notice how guys never fall for me, instead for my friends. I'm 5 6 1/2", thin, but I dance, my body is 31-24-34, and I have pretty long legs (about 32-33") I have medium to long hair, but I am pretty flat, no bum, not bust. I also have a slightly crooked front tooth and dimples on both cheeks. Please help me!
