FFS dan, does it make you feel good about yourself to be an arse to people on the internet? Twl, you look fab.
Cool, it's hard to say, as it's so individual. I'm 5' 9'' and I look tubby at a size 12, because I carry any extra weight weirdly, so my face gets really fat, my upper arms get chunky, and my hips get huge. While my legs stay very skinny and my arse is nonexistent. I have a friend who is the same height and is stunning at a 14 - 16. Because her weight is evenly distributed, and she has amazing cheekbones and a lovely defined jaw line. If I put on any weight I lose all definition on my face, it just becomes a big wobble of fat
.
The most important thing is, are you happy and healthy? If you're not, then address that, be it by losing weight or learning to be happier in yourself (sorry, that sounds really condescending, I don't mean it to be). If you do feel happy and healthy, then fuck what anyone else thinks.
