Think of it this way, back before the "big changeover", the smallest size you could buy was a 6. Now, the smallest size is a 0. When my mom was a teenager in the late 60's she was 5'9, 138 pounds and a size 14/12. Now, my little cousin who is a size 6/8 can wear my moms old clothes. Plus size clothes are the same way. There is the regular size 14 and 16, then there is the canadian plus size 14 and 16, which a 14 is a regular 16 and a 16 is more an 18. Then there is american plus sizes, which fit even bigger. Then there are "miss" sizing, where a 14 and 16 are more like a 10 and 12. But now they have miss/junior plus sizing, for which I have no idea which numbers mean what. Arghhh! Why can't they just put the bust or waist measurements on all pieces of clothing!
