Anna's is fantastic, and pretty much can alter anything you bring in.
I have brought multiple pants there (dressy and jeans) and have never had an issue with the final result. I have also had a few dresses and skirts done as well. On top of that I brought my wedding dress in to be fitted. I bought my dress as a sample so it needed multiple alterations, as well things I wanted changed (taking off some beading) and they also did the bustle- which was difficult on the dress I had.
I couldn't have been happier with everything they did! Although with specific employees some of the things I was saying was 'lost in translation' but usually one of the younger girls was around to clarify what I was wanting.
I will always bring my items to Anna's
