How do you calculate fabric consuption for woven shirt with flap pocket?

To calculate fabric consumption for a woven shirt with a flap pocket, first, determine the pattern pieces required for the shirt and pocket, including sleeves, collar, and placket. Measure the dimensions of each piece and account for seam allowances. Then, add up the total area of the fabric needed for all pieces, converting to square meters or yards as necessary. Finally, consider additional factors such as fabric width and pattern repeats, as well as a percentage for shrinkage and cutting losses to arrive at the final fabric requirement.
