If I could give Sinyan 10 stars I would. I brought my wedding dress to her just four days before my wedding, after having a not so great experience with another seamstress.

If I could give 10 stars I would. She delivered everything as promised! My dress was hemmed perfectly and she spent so much time making my daughter’s wedding dress her dream dress. I HIGHLY recommend her

The ladies who work here are so wonderful & helpful! I needed a rush order to alter my bridesmaid dress, I needed it a week from when I contacted them & they were able to fit me in the day that I called to do measurements AND they had it ready a day early! They took in the bust area & shortened the bottom & it’s perfect! I’m so thankful for them & it was definitely worth the 45 minute drive from where I live. I will definitely be coming back here in the future!
