Society has a screwed up way of defining each woman by the size of their jeans.
If you're a size 0, you are too skinny and need to eat a burger. If you are a size 12, you need to eat more salad and go for a run. There is no perfect size for society, and no one has the perfect body, but they will be damned if they don't try to change each and every one of us.
Yes, I am a size 12 and it is none of your damn business. I eat the food I want to, work out almost daily, and still cannot shrink down in size. I was a size 5 in high school and due to the media and bullying, I thought I was overweight then. Damn, I wish I could go back and slap myself silly! It all begins in middle school, or even earlier in elementary school.
As women, we see pictures of "sexy" women and what the men like. The media knows exactly what they are doing when they share those pictures. They are all trying to make a buck. I'm sure by now they also realize that they are not all inclusive and they are setting an unrealistic standard for most of the women of the world. If you are lucky enough to look like those models in the advertisements and on the television, by all means, flaunt your ass off! However, do not be surprised when I still strut my stuff in my size 12 jeans.
Yes, I am still a size 12 and no, it is not your business. I can fit into some size 10 dresses, but I also fit in a size 14 at some stores. Not all stores measure the same. I have ranged anywhere from a size 10 to a size 16 depending on the store. Those little boutique stores? Forget it. I can't get their pants above my thighs and their shirts over my boobs; it ain't happening. Thankfully, I have a very good support system, and I know that even though according to my BMI I am "obese," I actually have a pretty healthy body going on here. You can tell that I am active, but you can also tell that I enjoy pasta regularly.
Stop letting the media tell you how you should look, and learn to be comfortable in your own skin. It's important for you to love yourself; if you want to change the way you look, do it because you want to, not because the world is telling you to.
