It is easy to add a few inches to a skirt or dress pattern – especially around the hip area. This pattern illustration is from the Simplicity Sewing book published in 1940! You can see by the right hand of the illustration the garment will wrinkle across the hip or waistline where the fabric is being stretched to fit.
As much as you might fear cutting into your pattern, this pattern adjustment will make the pattern work for your body shape – If you really struggle to get snipping with your scissors, you can always copy the pattern onto cross and dot paper – and keep the original.
So here is what you do.
Cut down the front and back pieces from the hem to the neckline – then pivot the pattern apart into an inverted ‘v’. It helps if the top gap is small so that the pattern hinges.
Move the pieces apart far enough so that you have the extra space where needed along the hipline (the dotted line on this pattern)-
Make sure your hip/waist measurement includes seam allowances and 1 cm for ease.
Fill in the gap with paper or discarded tissue from the pattern.
Because you have altered the patten within the pattern outline, the original design will flow correctly.
If you need to decrease the measurements, simply cross over the two edges you snipped with your scissors, by the amount you need to reduce the pattern by.
