Hi. ive just turned 15, im 5'6 and abit (166 cm) and i weigh 65 kilos (143 lbs). is this average or am i overweight?
its just i have my formal coming up and id like to feel good with myself.
i just need to figure out whether to lose weight so i can look pretty in a new dress with out any lumpy bumps.
please write back.
thank you.

Yes you're a bit overweight. A girl of 5'6 should weigh somewhere between 110-130. It all depends on how active you are. If you do lots of sports and are very active, you should be healthy

you can look pretty in a dress whatever your weight.
just get the right dress for you.

130 whatever! It depends on your body type! I am 5'6 and weight 155 but I wear a size six! The second comment is right on! Just find the right dress for you!

So, I weigh 134 and am 5'7, but I do hella sports. I fit into a size 3. I think this girl is anorexic.
