I recommend Tina Spiegel (known in game as The Seamstress).
I have several shirts from her in a variety of styles and colors. She is very friendly, her shirts stand up to wear and tear, and she provides lifetime support for repairs if they are needed.
I have also purchased four vests from her, all custom (I love extra pockets), which are reversible, allowing me two vests in one.
You may contact her husband Charlie Spiegel (plays Edwin Haroldson) if you cannot reach her directly.
