Wedding Dress Alterations: What They Cost and What to Expect

Alterations are bought by 94% of American couples. That is exactly the same share who buy a wedding dress. The two numbers are identical because there is, in practice, no such thing as a wedding dress that does not need altering.

The median cost is $316 and the average is $410. That makes alterations more expensive than the median suit or tuxedo, which comes in at $181.

Despite being close to universal, this is the line item couples are most reliably surprised by, for a simple structural reason: the price is quoted after you have already chosen and usually already paid for the dress.

Why every dress needs altering

Bridal gowns are cut to a standard sizing template that corresponds to no actual person. Bridal sizing also runs differently from everyday clothing sizing, generally smaller, which is a common and unpleasant surprise at a first appointment and means nothing about your body.

Even a gown ordered in the correct size and hanging correctly on the shoulders will need the hem set to your height in your shoes. Anything with a train will need a bustle constructed so you can walk and dance after the ceremony. Those two jobs alone are the floor.

This is worth internalising before you shop, because it changes what the price tag on the rack means. The number on the tag is not the cost of the dress. The cost of the dress is that number plus a few hundred dollars you cannot yet see.

What the work actually involves

• Hem. Setting the length to your height in the shoes you will actually wear. The single most common alteration and the reason you bring your shoes to every fitting.
• Bustle. A system of hooks, loops or buttons that lifts the train off the floor for the reception. Priced by the number of points needed, so a long or heavily layered train costs more.
• Taking in the bodice. Adjusting the side seams and back so the dress sits properly through the torso. Straightforward on a simple bodice, involved on anything with boning or corsetry.
• Strap and shoulder adjustment. Setting straps to your torso length, which is far more variable between people than dress sizing accounts for.
• Cup and support work. Adding or moving internal support so the dress does not require separate undergarments.
• Structural changes. Adding sleeves, changing a neckline, reshaping a back. These are redesigns rather than alterations and are priced accordingly.

What drives the price

Three things, in roughly this order.

Layers

This is the biggest variable and the least obvious one. Hemming a single layer of crepe is one job. Hemming a gown with a lining, a tulle underskirt, a lace overlay and a beaded hem is four jobs, each of which has to be cut, finished and reassembled so the layers still hang together. The seamstress is charging for time, and layers are time.

Fabric

Chiffon, silk charmeuse and lace are slow to work with and unforgiving of mistakes. Beading and appliqué near a seam or a hemline often has to be removed by hand and reapplied afterwards. A structurally simple dress in a difficult fabric can cost more to alter than a more complicated dress in a stable one.

Silhouette

A slip or bias cut has almost no internal structure and is the cheapest shape here to adjust. A corseted basque waist, a boned bodice or a full ball gown with a crinoline is the most expensive, because taking one in means working through the internal structure rather than just the outer fabric.

This is the practical reason silhouette is a budget decision and not only an aesthetic one, and it is worth knowing while you are still choosing shapes rather than after. See the six silhouettes reaching boutiques for what each one involves.

Timeline

Alterations are typically two to three fittings over two to three months, with the first fitting commonly scheduled around two to three months before the wedding. Ordered gowns themselves usually take several months to arrive, so the practical shopping window is closer to nine to twelve months out than most people expect.

Rush work is the avoidable version of this cost. If you are inside the normal window you are paying for labor. If you are outside it you are paying a premium on top, and you have removed your own ability to walk away from a fit you are not happy with.

One practical note: your final fitting should be close enough to the wedding that the fit is current, but far enough out that there is room for one more adjustment. Leaving it to the last week removes your margin entirely.

Questions worth asking before you commit

1. Is the alteration estimate in writing, itemised, before I order the dress? This is the single most useful thing you can do. A boutique that will not estimate the work on a gown it is selling you is telling you something.
2. Are alterations in-house or referred out? Both are fine. In-house is more convenient and sometimes bundled. An independent seamstress is often cheaper and you keep the relationship if something needs fixing later.
3. Is there a flat fee, and what does it exclude? Some boutiques charge a single alteration fee that covers standard work and excludes anything structural. Find the boundary before you ask for sleeves.
4. How many fittings are included? And what does an additional one cost.
5. What happens if my size changes? Ask before rather than after. It is a normal question and any experienced fitter has heard it many times.
6. Do you have experience with this fabric? Particularly relevant for heavy beading, delicate silks, and anything vintage or secondhand.

A note on secondhand and vintage gowns

If you are buying secondhand, budget more here rather than less. You are buying a fixed size that was previously altered to fit someone else, so the work involved is usually greater than on a new order, and previous alterations can limit how much fabric is left in the seams to work with.

Have the alteration conversation before you buy, not after. It is still very often a large net saving, but the saving is smaller than the sticker difference suggests. More on this in buying a secondhand wedding dress.

The other thing nobody budgets for

Steaming. Bought by 30% of couples at a $154 median. A gown that has been boxed, shipped and hanging in a fitting room for months will need pressing before it is worn, and it is not always included in the alteration price. Ask.
