I really envy those TW models and those victoria secrets models, they are so slim and pretty.....
Angel face with devil's figure (direct translation from mandarin, haha!). Was wondering how to achieve that good figure. I always don't believe those slim ladies who said that they don't care whatever they eat, simple because they won't put on weight. Was wondering what are the ways in order to be slim.

1) Diet?
2) Exercise?

Suggestions please?
