If you have a car, definitely go see Estee out in Gaithersburg, MD. She is amazing and has altered both mine and a friend of mine’s wedding dress perfectly. I thought her customer service was outstanding- she will do as many fittings as it takes and without extra charge. Her prices were the best I found- her cap is $200 and she gives you an estimate right away. She has a ton of experience from what I can tell on Yelp – http://www.yelp.com/biz/estee-livioco-gaithersburg
And only ONE bad review, which is pretty awesome.
