What to Know About Prom Dress Alterations
Most prom dresses need at least one alteration — typically hemming ($15–$45) or taking in at the sides ($30–$85). Ball gown hems with multiple layers cost $60–$120 because each layer must be cut and finished separately. Book at least 6–8 weeks before prom to avoid rush fees that add 25–50% to the standard price.
Always bring your prom shoes to the fitting — heel height changes the correct hem length by 2 inches or more. Try the dress on before leaving the shop after every fitting, not just the last one.
