I hate the whole size thing.
At my lowest ever, 130 as an adult, before I had kids back in the late 70's I was 10 in womens, and an 11/12 in jrs.
Right now I'm a 12/14 in womens and 13/14 or 15/16 in jrs. depends on the brand.
But I see ladies my height, posting here, who weigh around 130 saying they are buying 2's, 4's, 6's, etc. I want to know where they are buying their clothes!
As far as shirts, I will never be any less than a large at the least because the girls just won't cooperate without reduction surgery.
It just gripes me to no end. When I was in high school, size 5 was skinny, 7 wasn't bad, if you were tall 9 was ok, anything over that was fat. *rolls eyes*
And what is with size 0!? 0 is nothing, have you disappeared? No offense to anyone who is a 0, but come on. 0!? I've even seen 00 and 000 on racks in some places.

With the way that the available clothing is sized in the area I live in, I will never be anything lower than a 10, because anything smaller than that, will mean I am TOO thin, and I would look like a twig.
