Depending on what you need tailored. I went to two places when I lived in Vienna. http://www.yelp.com/biz/youngs-tailors-vienna and http://www.yelp.com/biz/sofios-custom-clothiers-and-tailors-mclean-2#query:tailors Young's is cheaper (Korean lady works there). Sofio's is more expensive but they were the best tailors I have used.
