Mrs j did work for my bridesmaids drsss for my brothers wedding and also my wedding dress. Both times she was amazing and I didn’t not have an easy fix with the bridesmaids dress. She’s reasonably priced and quick!

As a plus size bride I was overwhelmed and almost horrified at my vast selection of dresses, but nothing fit exactly what I wanted. I found a poofy dress that was the color and fabric that I liked but needed TONS of alterations and changes. A friend suggested Jan to me, and I will be forever grateful. She understands the body and knows how the fit should be. She also had some really cool outside the box ideas for additions to the dress that I had never thought of, or even seen on another dress before. She did an amazing job and I refer everyone I know to her! You can not only trust that she will make your garment fit you impeccably but also trusting her with “the dress” was never in question. Thank you for making my wedding dress dreams a reality Jan!
