Wedding dress alterations cost $150 to $700 on average, with most brides spending around $450 for alterations. Bridal gown alterations are more costly than other dress alterations because the delicate fabrics and embellishments often require hand-stitching that is slower than machine sewing for other garments. Some bridal shops charge a flat alteration fee of $500 to $1,000, not including customizations like changing the neckline or adding a corset.
David's Bridal offers dress alterations for gowns purchased in their store or website. Most brides spend $150 to $500 for alterations from David's, with prices varying depending on the store location. David's guarantees the fit, or they will do another round of alterations at no charge.
