Taiwan 台灣

Looking for a tailor who can repair textiles. I have had the loop which holds the belt on a pair of my jeans come loose due to the thread breaking, as well as one of the buttons on a bag of mine break. Is there anywhere in Taipei I could get these repaired? I guess it shouldn't be too difficult for someone who knows what they're doing to fix this, but I have no clue where to go for something like this and I can't fix it myself. Any info is appreciated! :)
