Tailors in Abu Dhabi

After losing a lot of weight my shirts are starting to look ridiculous and thinking of getting them “brought in”/ refitted (I’m not sure what the right term is). Does anyone know a good place where I can get this done, somewhere I can go get measured up and shirts resized. In terms of pricing am I looking at like 15/20 dirhams a shirt or more like 60/70 dirhams? I have around 30 shirts I need altered. Does anyone know somewhere in AD that is recommended?
