How would you go in making a standardize size chart for women clothing?

We all know, women sizes differs between brands, models and countries. Men had the war to tha k for standardize sizing due to uniform requirement. Need a pair of pants? Hip size and leg lenght is all you need! For wonen though, it depends wich country, company, cut of pants. You'vegot hips sizing, waist size, various non descriptive leg lenght ( Regular, for short or tall legs), etc. I think it is just tedious to shop for clothing at this point. What's yourtakeon a solution to simplify all this spaguetti of size clothing?
