Does size really matter?

She's known for projecting an air of outspoken confidence.
But in an interview with Cosmopolitan UK, Khloé Kardashian recounts her battles with self-esteem and body image.
The Keeping Up With The Kardashians star confesses to the magazine: 

'I probably thought I was prettier before I entered the spotlight because being compared to somebody else every day does sort of beat up your spirit and soul.'

She says of her body: 'I don’t care what size I am; I care about how I look. If my jeans are tight and I have a little muffin top, then OK, I have to cut down on the carbs. I don’t expect to be a size 2 [a UK size 6] and nor do I want to be. I’m 5ft 10ins and I like being curvy.'

Unable to please her tormentors over her size,especially when compared with her sisters, she decided to ignore their jabs.
'I thought, ''Oh, my gosh, if I'm not good enough now...'' And that's when something clicked in my brain: I have to do whatever is good for me...I feel that I'm healthier [now], but I don't think I'm prettier thinner.
'I understand why so many people in this industry have eating disorders or want plastic surgery, and I'm proud I've done things the healthy way.'

Not being a size zero in the world today seems to be a crime against humanity, it goes against the grain,  and affects teenagers particularly. It's important to be healthy, skinny doesn't necessarily mean healthy.

Does a woman's size really make her cool and beautiful or being confident about yourself and staying healthy?
