You sound a bit similar to me, I'm like 5'2.5" and I usually wear size 10 on my bottoms and 6/8 on tops. I do feel fat and I know I'm a bit chubby, but I know I'm not fat if you get what I mean... I mean - it seems to me that people like us are normal, just on the upper side. :P We're not fat yet and we're not slim, I guess we may be called curvy... At least I've got the luck of having a proportional, hourglass body, which is always something that makes me feel better :P
