Wedding Dress Alterations: What's Done and When to See a Tailor
By TaVare · updated 2026-09-22
Altering a wedding dress is almost always about fitting a gown bought in a standard size to your exact shape – taking in the bodice, hemming the train and adding a bustle so you can dance. Because the dress is delicate, often beaded and built in several layers, and because you only get one shot on the day, this is among the most demanding alterations there is. Here is what actually gets done, what you can safely handle yourself, and when the dress should go to a professional.
Why a wedding dress almost always needs altering
Bridal gowns are made in standard sample sizes, and the shop normally fits you to your largest measurement – often the bust or hips – and takes the rest in. So almost every dress needs altering to actually fit. On the day, the fit is what you will see in every photo: a bodice that gaps at the back, or a hem you trip on, shows immediately. The good news is that most of it is routine work for someone who does bridal; the work simply has to respect delicate fabric and, often, both beading and boning.
- Take in the bodice: side seams, back seam or a corset back so the top sits close.
- Hemming: the dress is shortened to just skim the floor – in the shoes you will actually wear.
- Straps and shoulders: adjusting length or fixing them so they do not slip.
- A built-in bra or cups: support without visible straps.
- Bustle: lifts the train up off the ground for the reception.
Hemming is the hardest change – and why
Hemming is the alteration people underestimate most. A bridal skirt is often several layers – an outer fabric, one or more linings, maybe tulle and a horsehair-braided edge – and each layer has to be shortened evenly and rehung so the finished edge just kisses the floor in the shoes you will wear. If the edge is lace or beaded, you cannot simply cut it: the trim is lifted off, the layer shortened, and the lace or beading reapplied by hand so the border still reads the way the designer intended. On delicate silk and tulle, needle holes stay, so there is little room to redo it. That combination – many layers, a decorative edge, unforgiving fabric – is why the hem is usually the centrepiece of a bridal alteration.
Choosing a bustle for the train
If your dress has a train, you will want a bustle to lift it up off the floor for dinner and dancing – this is a decision you can make yourself before a fitting, and it shapes how the back of the dress looks all evening. Pick the style in advance, and bring your partner or a bridesmaid to the fitting so someone learns to fasten it; more attachment points give a smoother drape but take longer to hook up on the day. The most common styles:
- American (over-bustle): the train is lifted and fastened on the outside with hooks and buttons – visible and decorative.
- French (under-bustle): the train is tied up under the skirt, so it looks like draping from below – discreet.
- Ballroom bustle: many attachment points that make the train almost invisible and the skirt even all the way round.
- Single lift: one attachment point – fastest, but less precise on a heavy train.
What you can safely do yourself
Not everything needs a professional. There is real, useful prep you can and should do yourself.
- Buy the shoes and underwear you will wear before the hem is measured – the whole length depends on the heel height.
- Steam out creases by hanging the dress in a steamy bathroom; do not iron delicate or synthetic bridal fabrics, or beading, directly.
- Decide the bustle style in advance, so you know what you want by the time you reach the fitting.
- Secure a loose bead or hook by hand before it takes others with it.
- Measure yourself – bust, waist and hips – so you know what actually needs changing, and do not start too early.
Plan well ahead – with room for several fittings
Wedding dress alterations are rarely done in one go – a good fit usually comes from a couple of fittings where you adjust a little each time, with the final fitting close enough to the day that your measurements will not have shifted. Get started in good time rather than at the last minute, so there is room to try the dress on, walk and sit in it, and make small corrections without rushing. Try to keep your weight steady after the final fitting; a dress taken in to a boned bodice will not easily follow a big change either way right at the end.
When should the dress go to a professional?
For most brides, the honest answer is that the fit changes themselves belong with someone who does bridal – and that is not upselling, it is the nature of the garment. Taking in a boned bodice, adding a corset back, hemming a layered or beaded skirt evenly, sewing in cups, or reworking a beaded seam are specialist jobs where a slip shows on the one day you cannot redo. Simple prep – steaming, choosing the bustle, buying the shoes first – you can absolutely handle; it is the structural and decorative work that a professional earns their place on. Plan it in good time so there is room for fittings. You order online, and you see the price before you order.

Frequently asked questions
Does a wedding dress always need altering?+
Almost always. Bridal gowns are sold in standard sizes and usually fitted to your largest measurement, so the rest has to be taken in. Taking in the bodice, hemming the length and adding a bustle are the most common changes.
What is a bustle?+
A way of lifting the train up off the floor for the reception, using hooks and buttons. It can fasten on the outside (American) or under the skirt (French), with one or more points.
Can I hem the wedding dress myself?+
Rarely safely. The skirt is often several layers with a beaded or lace edge, and on delicate silk and tulle needle holes stay. Hemming is the change that most often should be done professionally.
When should the alterations be done?+
In good time before the day, with room for several fittings – but the final fitting close enough to the wedding that your measurements will not shift. Buy the shoes before the length is measured.
