Hi, Thank You for such lovely online tutorial.

I am trying to draft the bodice pattern from your online video. Whilst drafting, I try to understand the process properly. However, I struggle to understand why we have to divide the bust measurement by 20. Another question is why do we have to add 1.5cm twice to that divided measurement. Although I understand the second '1.5cm' is due to cup size.

Many Thanks

Re: Side Bust Dart Drafting (Bust circumference divide by 20?)

Dear sulochana94,

The division of the bust circumference by 20 has been found to give the best amount of intake for the bust dart trough trial and error. This is a formula that works best for most people, when drafting their pattern. According to the cup size, we should then add an amount not exceeding 2.5 cm to the bust circumference after dividing the bust circumference by 20.

For this dress form we are adding 1.5 cm for the cup size. We are adding this only once, after dividing the bust circumference by 20.

Happy sewing,

Nehzat
