Back Skirt Slit

Dear Kusuman,

There could be a few reasons that the slit would separate at the bottom when the skirt is worn.

The most common reason for this happening is when we have a belly that we are pulling the front of the skirt up on. This will cause the back of the skirt to be pulled on either side along the bottom. If we have a slit at the center back the slit will open up as a result. 

Another reason for the slit separating along the bottom of the skirt is that the skirt is too tight along the bottom. 

To fix the first issue, we need to let out some fabric along the center front waistline seam allowance of the skirt and lower the center back seam by about the same amount. The waistline will stay the same at the side seams, so we need to merge gradually towards them, on the front and back. This will result in the skirt falling properly on the body. Then we do a fitting to make sure we have let out and taken in enough on the front and back waistline seam allowances. If we have a belly we need to draft a full figure skirt block pattern.

To fix the second issue, we need to let out from the side seam allowances.

Hope this helps. 

Happy sewing,

Nehzat
