Sewing Pattern Sizes

We list sewing patterns by bust/waist size instead of the sewing pattern size because: 

• Sewing pattern sizes continue to change
• Ready to wear clothing sizes (modern rack sizes) don't match sewing pattern sizes
• Sewing pattern sizes are a higher number than the ready to wear sizes

Here are some examples of measuring sewing charts

Here is a sewing pattern chart from the 1960's to show you how the sewing pattern sizes changed in 20's years.
