Patterns Discussion / Re: upper bust measurement question

If you are trying to calculate how much of a full bust adjustment you need to make, the upper bust/under arm measurement is taken. Then the over bust/maximum circumference measurement is taken. The difference between the two is what defines the cup size. If you are greater than a B cup then you will have to make a FBA to the pattern.
Personally, I'd say that the upper bust is more useful for defining which size of pattern you need as this is determined by your build - I once bought a (UK) size 16 pattern for the bust size and the shoulders were hanging off me! There are lots of video tutorials out there showing you how to work this out and how to make a FBA. I even found one for T-shirt patterns that then 'lost' the adjustment in the side seam and hem (the hem at the front dipped but when worn it looked level).
