Formal Dress Alterations

Specialised structural work for formal & event gowns

Most girls pay around $500 – $900.Based on the last 55 formal dresses through the studio.

Where you’ll probably land

Little fixes

from $60

A few tacks, thread eyes, a mend, straps taken in, or cups added so you don’t need a bra. No hem.

Just the hem

around $410

The dress fits, it’s only too long. A simple skirt — one or two layers.

Hem and fit

$550 – $750

Hemmed, taken in so it sits properly, and usually cups added. The one most girls need.

Most girls

The big ones

$800 – $1,200

Lots of tulle layers, a corset back put in or taken out, or the dress taken in right through the zip.

Beyond this, we can do anything you can think of — just ask!

Isn’t “custom made” the answer? It depends who’s making it. Most custom dresses are cut to your numbers by someone who never meets you — you pick from a sketch, wait four to eight months, and don’t try it on until it turns up. Alterations are then charged on top, because a dress cut to measurements still has to be fitted to a body.

That fitting is the part that makes a dress look like yours, and it’s the part we do. It’s also why, when we build a gown from scratch, we fit it on you here before anything is cut — see below.

Three more things we do

Formal Ready

add $240 to your alterations

Everything sorted, not just the dress:

  • A tie and pocket square for your date, made from your own offcuts so he matches you exactly
  • A scrunchie from the same fabric
  • Steamed and pressed the day before, not weeks before
  • A proper garment bag to take it home in
  • A little emergency kit — tape, safety pins, spare thread eyes
  • If something goes wrong in the last week, you come straight to the front of the queue
Hem and fit, the usual$650
Formal Ready on top+$240
All of it$890

The tie and pocket square alone are $170 if you add them on their own.

The Formal Party

six or more — Formal Ready free for everyone

You’re all getting ready together anyway. Book as a group and we’ll fit the lot of you in one private session, out of hours, with nobody else in the studio.

  • Everyone pays for her own alterations, exactly as she would on her own
  • Formal Ready is included free for every girl — matching ties and pocket squares for all six dates, scrunchies, steaming, garment bags, the lot. That’s $240 each, $1,440 across the group
  • One private session out of hours, one collection day
  • Photos of you all in the studio, if you want them

Six girls at the usual $650 is about $3,900 — the same as booking separately, with $1,440 of Formal Ready thrown in. Booking you together saves us a dozen appointments, so we pass that back. More or fewer than six, just tell us how many.

Made for you, from nothing

from $5,000

For when nothing in the shops is right, or the dress in your head doesn’t exist yet. This is the custom-made worth having — the kind that gets fitted on you.

A pattern drafted to your body, a toile fitted on you before a scissor touches the real fabric, and a gown built from scratch to your design — by the same hands that rebuild wedding dresses every day of the week. Not ordered in. Not sized up from a chart. Made here, on you, and fitted as many times as it takes to be right.

Commissions open January to May, for a September to November formal. If you already know this is what you want, come and talk to us early in the year — we can’t start one in season.

Two things move the price

How many layers are in your skirt. Every layer gets hemmed and finished separately. A five-layer tulle skirt is five hems, not one.

Whether it comes in at the sides or through the zip. Sides in is usually a bust adjustment — we take it in where it needs it and leave the rest. Through the zip means the whole dress is coming down a size, so the zip comes out, the boning beside it gets reworked, and the lot goes back together. That’s a full resize, and it’s the one that catches people out.

You don’t need to know which is which. Send a photo of the back and one of the skirt when you book and we’ll tell you before you come in.

Two real dresses

The smallest — $60. Her dress already fitted. She needed thread eyes worked into the bodice to hold her straps in place. Nothing else.

The biggest — $1,170. Evelyn’s, from Lara Boutique. Four layers of hem, another layer removed altogether, every layer sewn into the split. Cups fitted, and the whole dress sized down through the zip. Scrunchie made from the offcuts.

Both real, both in the last twelve months, both priced as they would be today.

Come in early

Formal season fills from September. The sewing takes as long as it takes — it’s the appointments that run out. As soon as you have the dress, bring it in.

Why we cost more than a standard tailor: formal gowns are engineered garments — boning, layered skirts and beaded fabrics need bridal-level construction, not a quick take-in. Insides finished as cleanly as the outside.

Prices are a guide. Your final quote is confirmed at your fitting, once we’ve seen the dress and what it needs — and nothing is started before you’ve agreed to it.
