How much lining fabric is needed for women's suits?

It depends on the width of the digital printed fabrics and the style of suit.

As a rule of thumb, lining fabrics are generally 42 to 45 inches wide.

In this case, if it is a standard jacket and you are less than size 18, then you need 2.25 meters for the Jacket.

For the pants - you would need 1 meter for 1/2 lining and 2.5 meters for full lining.

For the skirt - if it is a straight skirt you would need 1 X skirt length. For very A line skirt you need 2X skirt length. For very flared you need 4X skirt length and for extreme flare you will need around 6X skirt length.

If you are larger than size 18, add 1/2 meter to everything.

Hope this is of help.
