Honestly there are not a lot of skinny ugly people in existence with the exception of some odd birth defects or results from an industrial accident. Most people just need to change their hair style to one that fits their face, remove or change to less clunky glasses (maybe even add some small cute ones with no frames) and take care of any acne problems and wear clothes that fit properly. I've never met a thin person that couldn't be attractive. Most of the time it's the hair though. What looks great on one person may make the next person look bad.
