What do you weigh? What size clothes RIGHT NOW?

I am 5'2" 138 lbs. with 23 lbs. to go to goal...My tops are mostly medium with a few smalls, which was an added bonus cause medium is OK with me and never expected to go smaller. My Easter dress was a milestone in that I fit into an 8 comfortably for the first time. In pants and shorts I mostly have 8-10s but when I bought new summer clothes, I found one pair of shorts in a 6 that fit which felt good cause that is loosely my size goal and the first thing I've owned in that size since high school. But I have a friend in fashion design and I asked her about this whole weird sizing thing....it really has nothing to do with OUR bodies or actual measurements or us being "in between" or anything. There really is no standard enforceable measurements for each size that applies across the board for all companies so each company sets their own standards; and it is further dependent on the measurements of the fit model they get when designing the garment to begin with. Plus the whole vanity sizing thing that keeps making the smaller sizes larger to boost the egos of people who want to say they wear such and such a size but don't have the body for the traditional size. So in my case, the bottom line I was trying to find out in this conversation, is that in general, (with all aforesaid variations and exceptions in mind), if I wore a size 6 in 1984 that roughly translates to a size 8, sometimes even a 10 today. The key is not to focus so much on the number on the size label as to find clothes you feel comfortable in and be happy with it cause no one sees the label but you anyway and if you look/act great, no one else is going to care about the number. You're more than that number anyway!!
