Yeah! Has anyone noticed that clothing from the 1940's and mid 1960's (thrift shops and such) it's hard to find a really big range of sizes in vintage wear?
Tells ya' something about the eating habits and how active were then!

I mean, I tried on a vintage size 10 dress and it was loose. I put on my size 12 dress back on it fit!?!

The mythical sz. 0 stills baffles me. 0 mean nothing, so a person is does not exist?!? In the fashion business a size 6 or 8 is the model sample size (kinda).

I have yet to come across a sz. 0 model since there is no such thing as a 0 person!?!
Unhealthy number, yes. It's really a freak number since there are a very, very, very tiny portion of healthy adult people who can wear this sz. Some of those people who wear 0-4 sz. clothing find it appalling that the size can only suggest 'sick and fragile' or misconceptions of 'anorexia and bulimia'.

Same with the word 'petite'.
It only means shorter length in arms, torso, and pant/skirt length not waist size or hip size. Petite sizes can range to a size 20 as well.

My sister wore a size 0-2 and she wanted to be a 6 or 8 (muscle) b/c she was the thinist of her diving team and it made her feel self-conscious in a bathing suit!

Goes to show sz's are not always right.
