Is the fabric torn and you want to patch it as discreetly as possible?
The seamstress will mend the torn as seamlessly as possible and get your garment back to use. The thread chosen for the repair is as close as possible to the colour of your garment.

If you want a visible patch on the fabric, choose visible mending/patching.

Extending the life of a garment is always worthwhile. The longer you wear a garment, the lower its environmental impact and carbon footprint.
By choosing to repair your clothes instead of buying new ones, you're doing your bit for more sustainable future - congratulations 👏
