I am sewing costumes for my entire family (15 total costumes!), and I am having problems with sizes. I bought patterns according to off the rack sizes for each member, but when I went to make the muslin patterns, they weren’t even nearly big enough. I now look at the waist and hip measurement, and those don’t even match up.
Is it true that pattern sizes are not off the rack sizes? Do you use the largest measurement on the pattern to the size of your person and then try to alter from there? Any suggestions on what I should do first? Thank you.

It is true that sewing pattern sizes and off the rack sizes are not similar at all. When sewing with a commercial pattern, the only real way to determine the correct size to make is to take body measurements.
When selecting a size to make based on the measurements, you will want to pick the size that all (or most) of the measurements line up with. If there is one that doesn’t match up with the rest in a certain size column, you can grade the pattern up or down in size as necessary.
For example, if a bust and hip measurement fall in a size 8 but the waist is a size 10, you can gradually grade the cutting line from and 8 to a 10 from the bust to the waist, and then back down from a 10 to an 8 from the waist to the hips.
Hope this helps!
