That is so true! Each clothing manufacturer seems to have their own basis for size. I have to try on each and every thing I purchase and have even been known to walk out of a store with 3 different sizes of clothes. I have also noticed that over the years they downsize the numbers to appeal to people's vanity. For instance what 15-20 years ago was called a women's plus size 20, is now called a ladies size 16 or 18, when actually they are the same size. It's a way for them to make more money selling people clothes so they think they're slimmer. Which in my opinion just makes clothes shopping downright frustrating at times.
