Not so much repair. I mostly by clothes that do not need to be repaired. I have only repaired a few exceptions - suits so extraordinary that I coludn´t resist them.
But I have spent some money at my tailor adjusting the length of the arms or legs. Some jackets and trousers have also been adjusted in width. Easy adjustments (a small change in waist or length of trousers) and moving buttons I do myself, or I ask my wife to help me.
Then you must add the cost for dry clean of course.
