A formal dress should feel as polished as the occasion itself. Alter My Dress provides formal dress alterations in Philadelphia and Montgomery County, PA, with couture-level tailoring for ball gowns and special-occasion dresses.
Whether your dress needs a precise hem, bodice adjustment, sleeve alteration or more extensive resizing, our design team evaluates its fit, construction and detailing before recommending the appropriate work. We alter dresses for galas, black-tie events, weddings, award ceremonies, military balls and other formal occasions, with careful attention to proportion, comfort and movement.

Formalwear often combines structured bodices, fitted silhouettes, delicate fabrics, layered skirts and detailed embellishments. Alterations are planned around the dress’s construction and the way it should fit and move.
The hem can be adjusted for your height, shoes and the dress’s intended length. This may involve multiple skirt layers, lining, lace borders, horsehair braid or other specialty finishes.
A formal dress may be taken in or let out where its construction and seam allowance permit. Adjustments can improve the fit through the bust, waist, hips and back.
Straps may be shortened or repositioned, and sleeves can be adjusted for fit and movement. Neckline or coverage adjustments may also be possible depending on the dress.
Zippers, hooks, buttons and other closures may be adjusted or replaced when needed to improve fit and function.
Full skirts, fitted skirts, overlays, linings and tulle layers may require individual alterations to maintain the dress’s proportion and movement.
Ball gowns may require specialized work because of their structured bodices, voluminous skirts, internal support and multiple layers. Each component is evaluated before alterations begin.
Lace, appliqués, sequins and beadwork may need to be removed and reapplied so alterations can be completed without disrupting the original design.

Bring the formal dress, shoes and any foundation garments you plan to wear. The design team evaluates the fit, length, construction and movement of the dress while you are wearing it.
We identify the adjustments needed to improve the dress’s fit, proportion and comfort. Any limitations created by the fabric, seam allowance, structure or embellishments are explained during the fitting.
The recommended work, estimated cost and fitting schedule are reviewed before alterations begin. The timeline depends on the dress and the complexity of the requested adjustments.
The approved alterations are completed in stages. Additional fittings may be needed for structured bodices, significant resizing, layered skirts, ball gowns or detailed handwork.
At the final fitting, we check the dress with your shoes and undergarments to confirm its length, fit, comfort and movement before the event.

Schedule your first fitting approximately four to eight weeks before the event whenever possible. This allows time for the initial fitting, alteration work and any necessary follow-up fittings.
Ball gowns, extensively beaded dresses, major resizing and garments with multiple skirt layers may require additional time. Appointment availability also becomes limited during wedding, prom and holiday seasons, so booking early is recommended. If your event is approaching quickly, use the appointment form to check whether rush service is available.
The cost of formal dress alterations depends on the garment’s construction, fabric, number of layers, embellishments and the type and extent of the adjustments required. A simple hem or strap adjustment generally involves less work than resizing a structured bodice or altering a layered ball gown.
Alter My Dress must evaluate the formal dress while you are wearing it before providing an accurate quote. The recommended alterations and estimated cost will be reviewed during your fitting before work begins.

Formal dress fittings are available by appointment at both Alter My Dress locations. Bring the dress, event shoes and the undergarments or shapewear you plan to wear so the length and fit can be evaluated accurately.

“They did a wonderful job on what I wanted done on my wedding dress! Me and my mom really loved it. She took care of covering the chest area for me very good that it bended in. Definitely a 5 star”
