Bridesmaid Dress Alterations: What Can Be Changed, Cost and Timing

Bridesmaid dresses are rarely made for the people who wear them. They’re usually chosen as a set, ordered in standard sizes (often online), and then expected to fit four or five very different bodies on the same day. So it’s no surprise that most of them need a little work before the wedding.

The good news is that plenty can be fixed. A hem that drags on the floor, straps that keep slipping, a bodice that gapes when you bend over to fix the bride’s train. These are everyday jobs for a good bridesmaid dress tailor. Some changes are harder, though, and a few aren’t really worth doing at all. Below, our alterations team walks you through what can be changed, roughly what it costs, and how to time it so nobody is scrambling the week before.

Do Bridesmaid Dresses Usually Need Alterations?

Most do. It’s unusual for a whole bridal party to try on ready-made dresses and have every single one fit perfectly. Size charts are built around one set of measurements, and real bodies don’t follow them. One bridesmaid might match a size 12 at the bust and a size 10 at the waist. Another might be 157cm tall wearing a dress cut for someone 172cm in heels.

Small fit problems are easy to ignore in a fitting room, but they show up on the day. A hem that’s 3cm too long gets stepped on during the walk down the aisle. Straps that slide off the shoulder get tugged at all night, and you’ll see it in the photos. Comfort matters too. Bridesmaids stand through the ceremony, the group shots and often the speeches, so a dress that pinches or needs constant adjusting makes for a long day.

What Can Be Changed on a Bridesmaid Dress?

Here are the jobs we see most often, starting with the simplest.

Hemming

This is the most common bridesmaid dress alteration by a long way. The key is to have the hem pinned while you’re wearing the exact shoes you’ll wear on the day. Even a 2cm difference in heel height changes where the dress falls. For floor-length styles, most people like the hem to sit just off the floor so it skims rather than drags.

Many bridesmaid dresses are made from chiffon with two or three layers, and each layer is hemmed separately with a fine rolled finish. That takes more time than a single-layer hem. Dresses with a lace or beaded edge are trickier again, because cutting the bottom off would remove the detail. In that case the dress is often shortened from the waist instead, or the lace edge is carefully lifted and reattached higher up.

Taking In the Bodice, Waist or Hips

If a dress is loose anywhere, it can usually be taken in through the side seams or the back seams. This is especially important for strapless and corset-style bodices, which rely on a snug fit to stay up. If you find yourself hitching the dress up during the fitting, it needs taking in.

Shortening or Adjusting Straps

A quick and inexpensive fix. Lifting the straps also raises the neckline slightly, which helps if a V-neck or cowl sits lower than you’d like or gapes when you move.

Adding Bra Cups or Extra Support

Sewn-in cups are a small change that makes a big difference, particularly in backless, low-back or thin-strapped dresses where a normal bra won’t work. A tailor can also add a modesty panel to a deep neckline, or a discreet strap to a strapless dress for peace of mind on the dance floor.

Letting a Dress Out

This is where things get harder. A dress can only be let out if there’s spare fabric in the seams, and many mass-produced bridesmaid dresses have very little, sometimes as little as 1cm. When there isn’t enough, there are still options:

• A lace-up corset back. The zip is replaced with loops and a ribbon, which adds a few centimetres of room and is adjustable on the day.
• Side panels or inserts. Matching or contrasting fabric is set into the side seams. This works best when the colour can be matched closely.
• Using fabric from elsewhere. On a long dress, fabric can sometimes be taken from the hem or an inner layer.

If a bridesmaid is between sizes when ordering, it’s almost always safer to size up. Taking a dress in is far easier, and usually cheaper, than letting it out.

Adding Straps or Sleeves

A strapless dress can have straps added, and some styles can take simple sleeves or a cap sleeve. The challenge is finding a fabric that matches. If the dress is long, the tailor may be able to use fabric from the hem so the colour and texture are identical.

Changing the Length or Style

Bigger changes are possible too. A maxi dress can be shortened to midi length, a high split can be lowered or closed, and a zip can be replaced or moved. These take more time and cost more, but they can turn a dress one bridesmaid felt unsure about into one she’s happy to wear.

What Is Hard to Change?

A good tailor will be upfront about what isn’t worth doing. These are the situations where alterations are limited or expensive:

• Going up more than a size. Unless the dress has generous seam allowances, there’s only so much room to find.
• Heavy beading or sequins. Every bead along a seam has to be removed by hand and reattached after the seam is changed.
• Pleated or draped bodices. Folds are often sewn into the structure, so taking them in can mean taking the bodice apart.
• Stretch and jersey fabrics. These can be altered, but they need the right machine and finish so the seams still stretch.
• Velvet and satin. Both show old stitch marks and press marks, so there’s less room for trial and error.

Sometimes the honest answer is that reordering in a different size costs less than altering. If your tailor suggests that, it’s worth listening.

How Much Do Bridesmaid Dress Alterations Cost?

The price depends on the fabric, the number of layers, any lace or beading near the seams and how much needs changing. As a rough guide, these are typical price ranges for common jobs in Auckland:

Alteration	Typical price range (NZD)	What affects the price
Hem, single layer	$40 – $80	Fabric and hem finish
Hem, multi-layer chiffon or tulle	$80 – $180	Number of layers
Hem with lace or beaded edge	$120 – $250	Whether the edge is lifted and reattached
Take in side seams or bodice	$60 – $150	Boning, lining, zip position
Shorten straps	$25 – $60	Whether straps are adjustable or sewn in
Add bra cups	$25 – $50	Lining access
Add straps or sleeves	$60 – $180	Finding matching fabric
Let out or add a lace-up back	$90 – $220	Seam allowance available
Replace a zip	$50 – $100	Zip type and length

For most bridesmaids, a hem plus a small take-in lands somewhere between $100 and $250. The best way to know for sure is a fitting. At Alter Me, we pin the dress on you and give you a quote in person, because a price given without seeing the dress is only ever a guess.

Who pays? In most bridal parties, each bridesmaid pays for her own alterations, the same as she would for her shoes. Some couples choose to cover the cost, especially if they’ve picked a style that needs a lot of work. Either is fine. Just agree on it early so nobody is caught off guard.

What pushes the cost up? Multiple layers, lace or beading near the seams, a dress that needs work in several places, and rush jobs. Leaving enough time is the easiest way to keep the price down.

When Should You Get Bridesmaid Dresses Altered?

Timing is where most bridal parties come unstuck. Go too early and bodies change. Leave it too late and you’re paying rush fees or settling for a dress that doesn’t quite fit. This timeline works well for most weddings:

When	What to do
5–6 months before	Choose and order the dresses. Online and overseas orders can take 8–16 weeks to arrive, so allow extra time.
As soon as they arrive	Try every dress on. Check for faults, colour differences and sizing while you can still exchange them.
8 weeks before	First fitting. Bring the shoes and underwear you’ll wear on the day.
3–4 weeks before	Second fitting, if needed, to check the changes.
1–2 weeks before	Collect the dresses, try them on one last time and have them pressed.

Spring and summer are the busiest months for weddings in auckland, roughly October to April. If your wedding falls in that window, book your fitting a little earlier, as tailors fill up quickly.

How long do the alterations themselves take? A simple hem can be done in a week or two. A full bridal party, with several dresses each needing a few changes, usually takes two to four weeks. In peak season it can take longer, which is why that eight-week starting point matters.

For the bride’s own gown, the timing is a little different. Our wedding dress alterations cost and timeline guide covers that in detail.

How to Prepare for a Bridesmaid Dress Fitting

A little preparation makes the fitting quicker and the result more accurate.

• Bring your shoes. This is the one people forget most, and it decides the hem length.
• Wear the right underwear. The bra, strapless bra or shapewear you’ll wear on the day changes how the dress sits.
• Know the brief. Has the bride asked for all hems at the same length, or a particular neckline? Check before you go.
• Book together if you can. Seeing the bridal party at one appointment makes it easier to match hem lengths and strap heights across the group.
• Speak up. If something feels tight when you sit or raise your arms, say so. Bridesmaids move a lot more than you’d think.

Ordering Bridesmaid Dresses Online? Read This First

A lot of bridesmaid dresses are now bought online, often from overseas. That can save money, but it puts more pressure on the alterations. A few things help:

1. Order by the largest measurement. If the size chart puts you in a 10 at the waist and a 12 at the bust, order the 12. It’s easy to take in and often hard to let out.
2. Order all the dresses together. Dresses from different batches can be slightly different shades, which shows up clearly when everyone stands side by side.
3. Check the fabric description. Chiffon, satin, stretch crepe and sequins each alter differently. If you’re unsure, ask your tailor before you buy.
4. Allow for delays. Shipping to New Zealand can be slow. Build in a buffer so the dresses arrive at least ten weeks before the wedding.

Altering vs Custom-Made Bridesmaid Dresses

Altering a ready-made dress is the right choice for most bridal parties. But if your bridesmaids have very different shapes, or the style you love would need major changes on every dress, a custom-made dress can work out simpler. Each one is made to the bridesmaid’s measurements from the start, in the same fabric and colour, and you can even vary necklines or straps to suit each person while keeping a matching look.

Our general dressmaking service can make bridesmaid dresses, mother of the bride outfits and formal dresses to measure.
