FAQ's

  • Do you offer both standard and bridal alterations at this location?

    Yes. Our East 87th St studio provides expert standard alterations for everyday garments as well as specialized bridal tailoring to ensure wedding gowns and bridal party attire fit perfectly.

  • How long will my fittings last? How many fittings will I need?

    Our standard fitting appointment lasts for 30 minutes. If you feel you might need more time or have specific requests, please feel free to ask our friendly staff at the front desk, and we'll be happy to accommodate your needs based on appointment availability.

    The number of fittings required depends on the complexity of your garment and the alterations needed. Typically, we aim for one fitting and then proceed to your garment's final try-on and pick-up. However, in some cases, a second fitting may be necessary. We'll always communicate this with you before moving forward with any additional alterations.

  • What alterations can be made to my garment?

    The alterations that can be made to your garment depend on your specific needs and preferences. At Alts, we offer a wide range of tailoring services, including but not limited to: Adjusting fit, hemming, sleeve alterations, darting, zipper and button replacement, lining repair or replacement, repairs and patching, customizations, and more! To determine the alterations needed for your garment, we recommend scheduling a fitting and consultation with our experienced team. We'll assess your garment and discuss your preferences to provide tailored recommendations for achieving your ideal look and fit.

  • What should I bring with me to my fitting?

    When coming in for your fitting appointment, it's helpful to bring the following items with you:

    1. The Garment to be Altered: Please bring the specific clothing item that you would like to have altered. This allows our fitter to assess it accurately and make precise recommendations.

    2. Undergarments: Wear the undergarments or shapewear that you intend to pair with the garment. This ensures that the alterations take into account the fit with your preferred underlayers.

    3. Shoes: If your garment involves alterations to the length, such as hemming pants or a dress, bring the shoes you plan to wear with it. This helps our fitter determine the appropriate length for your garment.

    4. Accessories: If you have accessories, such as a belt or jewelry, that you plan to wear with the garment, it can be helpful to bring them along to see how they complement the final look.

    5. Ideas and Preferences: If you have specific ideas or preferences for how you want the garment to fit or look after alterations, feel free to share them with our team during the fitting. This helps us understand your vision and tailor the alterations accordingly.

    By bringing these items to your fitting, you'll help our team provide you with the best possible guidance and ensure that the alterations meet your expectations. Your input and collaboration are essential in achieving the ideal fit and style for your clothing.

  • How far in advance should I schedule my fitting? Do you offer rush services?

    You can book an appointment as far in advance as you'd like. We recommend you come in as soon as you know you need alterations so that we do not have to rush anything! However, we understand that sometimes we need things done quickly! We will do our best to accommodate rush requests and the team will communicate with you transparently on what can be done.

  • "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!"

  • "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."

    Golzar S.

  • "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."

    Ed F.

  • "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."

    Kate D.

  • "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."
