  • Barie S.

    "Extremely grateful for the tailors at Alteration Specialists! I had a leather jacket with zippers on the bottom of the sleeve, which I thought would make it impossible to fix, but they proved me wrong!"

  • Stacie B.

    "Alteration Specialists are literally the BEST! They fitted my rehearsal dinner dress to my body like a glove! Also structured my Mother’s dress for my wedding perfectly for her and even made her a matching mask! I’ve had them alter many items now and it is always worth every penny because the items are absolutely catered to your form. They are truly artists!"

  • Moti A.

    "The studio is so gorgeous and feels extremely high end. I felt very confident leaving my high end luxury designer pieces in the right hands. Galina and Maya are the best!!!!"

  • Stuart G.

    "Very happy with my experience at Alteration Specialists. It is worth every cent. You get what you pay for, which is top notch tailoring and quality. Highly recommended."

  • Golzar S.

    "They altered a dress to fit me perfectly with a day of turnaround. He paid incredible attention to detail and was meticulous in his work. I am so grateful for his attention to detail, interest in making it perfect, and his fast turnaround."

  • Soey A.

    "Beautiful, FAST, detailed, efficient service. I came in on a Tuesday, panicked because I needed a couture gown altered in under a week for a wedding. Bibi immediately made me feel comfortable. She listened to exactly what I wanted and knew what to do to make an already beautiful gown extraordinary, and she managed to do it in 3 days and called to say it was finished early. The work speaks for itself, but I had an amazing experience throughout the whole process and will definitely be returning for all my tailoring needs."

  • Pablo G.

    "Went to Alteration Specialists to get two denim pants altered. The service was exceptional. Sinai was professional, efficient and was able to accommodate a quick turnaround for the alterations. Highly recommend."

  • Elle L.

    "Say goodbye to a hot stuffy room trying to carefully undress with pins everywhere. This place is super cute, air conditioned, and offers refreshments upon arrival. Must schedule an appointment!"

  • Ed F.

    "Highly recommend Alteration Specialists for tailoring needs. I left two very expensive suits to be altered and they took such good care of them They knew exactly what needed to be done to enhance the fit and I was very happy with the final result."

  • Kate D.

    "Just a quick update that I've now been coming to Alterations Specialists in Tribeca for about a year, and they remain so wonderfully consistent. The last few times I've been in, I've been helped by Bibi--she is so lovely and so so good at what she does. She has a great eye for how clothes should hang and what tailoring is needed. All of the front desk folks are always lovely too. It's the only place I trust with my special designer vintage finds."

  • Georgina F

    "I don't often write reviews but felt that I had to here. Myrna is an angel sent to this planet to save us all when we need something altered in any way. I had a beautiful gown for my brother's wedding that needed alteration and the wedding was the very next day. I brought the gown in at 6pm, and she had it PERFECTLY altered by 10am the next morning! On a weekend! To top, it's flawless. It fits me like a glove, and her work is unparalleled. I've lived in NYC my entire life and have never had anyone alter my clothes this well."
