Prevention is better than to cure
In terms of repairing, it’s simple. We do have a sewing kit of course, but to prevent is better than to cure. What usually happens, is that a lot of people are a little too tight in their elbows, or too tight in the arm specifically, and then it starts to wear at the elbow of your respective garment. Because a lot of people have desk-jobs, they stay with their jacket on, they have their arms on the table when they are typing for example, but that puts strain on the fabric as well. So I would recommend removing your jacket, especially when you’re driving. That’s very, very crucial by the way. Because every time you sit, you’ll get creases, wrinkles in the back from sitting. So always take off your jacket!
