From the very beginning, Theresa made me feel completely at ease throughout the entire process.

esa hopped on a FaceTime call to walk her through it! I also had my moms wedding dress made into a cocktail dress that I wore to the rehearsal. It turned out absolutely perfectly and was such a special part of the wedding weekend. I also had her steam and press both my dresses and she bagged them up perfectly and pickup was flawless. Highly recommend!
Ms. Theresa is EXCELLENT at what she at her craft. As a Black bride, there is always concern if your seamstress will alter your dress to fit YOUR body and YOUR color. I am proud to...
say Theresa did a phenomenal job. She even pulled tulle out during our appointment to match my skin tone for the mesh chest area. A bit pricey, but completely worth it!

I’m so grateful and will be definitely be recommending her to future brides!

her work. She took a lot of time each visit that I had to really walk us through the process, how she was going to go about making the alterations that were needed, and more. At my final fitting when it was all done, she had 1) done an amazing job with the bustle and 2) walked my mom through how to do the bustle on the wedding day. She spent a lot of time and had a lot of patience in making sure my mom and I were knowledgeable and comfortable with what was needed on the day in order to do it. She has many years of experience and I am very happy with the level of precision, detail, and service she provided.

ding date, but Theresa was able to work with the timeline and made my dress fit like a glove. I had a long train, so I was worried about how the bustle would look and last throughout the night.

going to provide the lift I wanted. She offered a much better alternative at a good price. I felt like I was at my grandma's house the whole time. She sewed as well and Theresa treated me with the same amount of care. She pressed and steamed my dress and she keeps the dress there until a couple days before the wedding. It was so helpful. She even offered great tips on how to keep my dress nice during pictures by using a shower curtain. She has YEARS of experience and I would highly recommend using Theresa!!

7 point bustle, and totally customized the back. It turned out beautifully and the dress fit me like a glove. Would recommend her for anyone looking for a trustworthy seamstress
Theresa is a miracle worker! All of my dress dreams came true with her help!
Theresa went above and beyond! This seamstress worked with me and the wedding dress boutique under unusual circumstances. The boutique had measured me incorrectly, resulting in a s...
ignificantly short ballgown! Theresa was able to walk me through how to handle this extreme error. When I began having problems with the boutique, she was willing to speak with them. When it was discovered that the new dress did not have the panels I paid for, leaving my dress partially nude, Theresa worked a miracle. She spoke with the boutique, got the new dress and managed to fix this additional mistake, one week before my wedding! If you want a person who will go the extra mile and ensure you walk down that aisle in your dream wedding dress, I highly recommend Sew Ridiculous!
Teresa was great. Her work looked beautiful and really appreciated her time.
Amazing! Highly recommend! Very respectful, courteous, knowledgeable and timely.
