The Trousers

I am working through the Pattern Course online and with the Pattern Drafting Metric System book.

On the SB Waistcoat WCT01 video at about 14mins in Rory talks about how the waistcoat sits against the waistband of the trousers. He says that this position is in relation to high rise trousers and that all the drafts in the book are for low rise.

How do you convert the low rise pattern to a high rise pattern?

1. Rise

2. Waist

3. Fly Angle (Including max fly angle reduction)

4. Darts

5. Points 21,22 and 23

6. Anything else

Thanks
