What each fix costs

Hems are on the posted price list above. Other changes, like straps or a take-in, are priced by your tailor at the fitting and added to your quote before anything leaves. See dress alteration prices.

Fit the whole party at one address

Book one visit at one address and list every dress so we hold enough time. Each dress gets its own QR tag and photos, and each line is on the quote.

Timelines

Promised turnaround is 7–10 days after the fitting, or under 5 days with rush (+40% on rushed items). Book once everyone has their dress and shoes, and leave a buffer before the event.

Fabrics that need extra care

Chiffon and other layered skirts are hemmed layer by layer, which is why each extra layer has its own price. Sequined or beaded hems may need trims moved by hand; your tailor will tell you at the fitting.

Splitting the bill

There is one quote per visit. If the party wants to pay separately, decide who books before the visit.

Sometimes, if there is seam allowance inside. Your tailor checks at the fitting.

Hemming your pants shouldn’t take two subway rides.
