Models??

are models today good role models for teenagers and younger children as they all now worry about what they look like because of todays models beeing so thin ???

Nope, not at all.
All models have to be tall and super skinny and I don't think that makes a good role model, I think anyone at a healthy weight should be able to model. A role model should never depend on a persons looks, it should be about their personality and inner beauty. I don't think teens should look up to models or celebrities because most of them are so fake, barley any of them are real anymore, its sad really. Most of the models today look like they haven't eaten since last year, pretty much skeletons with nice clothes, make-up, and hair. I don't find skeletons beautiful at all, I don't know who would.

Sends the message, you're not a 'model' / attractive person unless you're thin and in some cases, very thin - so No, not a positive message.

NO NT AT ALL,
MODDELS ARE WAY TO SKiNNY AND DEY like don't EAT AND PEOPLE GOTA EAT..
AND IF YOU WEAR like A B CUP YOU CONSIDER A 'PLUS SiZE' AND SOMETiMES YOU CANT CONTROLL YOUR BODYY SiZE!
