I found a site that showed you how to repair a tear in clothing.
Read all about it here: http://diyfashion.about.com/od/mendingandalterations/ss/MendSeam_4.htm
EXTRACT:
Start by inserting your needle where the seam is still closed, about ½ an inch from where the seam has started to open. Start to sew above the existing seam that is still in place. Begin sewing toward the open seam. Sew a few stitches diagonally down so that you work your way to just below the original seam stitch. When you get to the open part of the seam, lay both sides of the seam together and sew in a straight line just below the old seam’s holes.
It may help to use straight pins to hold the open seam together while you sew. If pins make you nervous, masking tape can be substituted by folding it over the top of the seam.
Sew below the holes from the old seam thread to ensure that these holes do not show up while you’re wearing the garment. These holes should be part of the seam, not the visible part of your garment. Continue sewing in small stitches all the way to the other side of the open seam, using the old holes as a guide for a straight line.

I had a look at my skirt and the repair was slightly different so my mum and I worked out the best thing to do. I chose the same colour cotton as the dress and threaded my needle. I made a double stitch to start and then made the same size stitches the same distance apart along the line of the repair, carefully linking the embroidery on both sides. I ended off with a double stitch. Afterwards I showed my mum to see what she thought and neither of us could find the repair. So funny.
