Easy Empire Waist Dress Tutorial: 7 Steps From Measure to Hem

The part that decides whether the dress hangs right is not the gathering and it is not the zip. It is where you put the seam. Two centimetres too high and the seam cuts across the bust; two centimetres too low and the skirt starts at your natural waist and the whole shape disappears.

So measure first, then draft, then cut. The sewing after that is straight seams and one curve.

What You Need to Sew an Empire Waist Dress

For a dress in a woven fabric you need 2.5 metres of 150 cm fabric for most sizes up to a midi length, 3 metres if the print has a large repeat or the skirt is full length. For jersey, 2 metres is usually enough because the skirt can be cut narrower. Add a 40 cm invisible zip, a quarter metre of lightweight fusible interfacing for the neckline facing, matching thread, and 2 cm elastic if you are making the casual version with an elasticated back.

The tools are ordinary: pins, fabric scissors or a rotary cutter, a tape measure, a ruler, tailor’s chalk, a sewing machine with a zip foot, and an iron that you will use more than you expect. A dress that has been pressed after every seam looks twice as expensive as one that has not. Fabric choice then decides how much of the method applies, and the table below is the short version.

Step 1: Measure the Underbust, Not the Waist

Take a high bust measurement around the chest above the bust and under the arms, a full bust measurement around the fullest point, an underbust measurement around the ribcage where a bra band sits, and a length from the underbust down to where you want the hem.

The underbust is the number this dress is built on. It sets the seam, the bodice depth and the point where the skirt is gathered. If you take only one measurement, take that one.

Wear the bra you will wear with the dress, and stand normally rather than holding your breath. A padded bra can move the underbust line by 2 cm or more, and that is the difference between a seam that sits under the bust and one that sits on it.

Why the Natural Waist Is the Wrong Number

A standard dress pattern is drafted to the natural waist, the narrowest point, roughly 25 to 30 cm below the shoulder. An empire pattern stops 20 to 25 cm below the shoulder, at the ribcage under the bust, and everything below that is skirt.

If you draft from your waist measurement and simply cut the bodice short, the bodice will be baggy at the ribcage, because your ribcage is wider than your waist. That is why the underbust has to be measured separately.

Step 2: Draft the Bodice to Your Underbust

Start from a basic bodice block that fits your bust, or trace a commercial bodice pattern you already own, and draw a horizontal line across it at the underbust minus 2 cm. That line is your empire seam, and everything below it becomes skirt.

Add shoulder darts or a bust dart from the side seam, the same shaping used in a square neckline dress where the neckline carries the fit,, whichever your block uses, and end the dart 2 to 3 cm below the apex. A dart that runs into the apex creates a point on the bust that will show through any fabric.

Then add your seam allowance to the pattern piece, not to the fabric. Use 1.5 cm at the side seams and the shoulder, 1 cm at the neckline and armhole, and 1.5 cm at the empire seam. Commercial patterns from the big brands and free PDF patterns from independent designers usually already include 1.5 cm, so check the instruction sheet before you add anything.

Drafting the Dartless Jersey Version

A jersey bodice needs no darts at all, because the stretch does the shaping. Cut a front and a back that fit the bust with negative ease of about 5 cm in total, that is, the pattern measures slightly smaller than your body.

Make the bodice a simple rectangle with an armhole cut into it, ending at the underbust line, and gather the skirt into the bottom edge. The fabric does the rest, and the seam sits flat without a dart to fight it.

Step 3: Cut the Fabric and Mark the Seam

Lay the fabric out, check the selvedge is straight, and place the pattern pieces on the grainline with the arrows parallel to the selvedge. A bodice cut off grain will twist and the side seam will swing to the front by the end of the first wear.

Mark the empire seam line on the wrong side of both bodice pieces and both skirt pieces with chalk or a line of tailor’s tacks. That line is what everything else is matched to, and on a dark fabric a tailors tack is often the only mark you can see.

Cut the bodice front, bodice back, two skirt panels and the facings. If the skirt is wider than the fabric, cut it in two pieces and join them at a side seam rather than making the front narrower.

Step 4: Sew and Fit the Bodice

Sew the bust darts, the shoulder seams and the side seams, and press every seam as you go. Press the darts towards the centre and the side seams open. Then attach the facings at the neckline and armholes with right sides together, clip the curves, turn them to the inside and understitch. Understitching is a line of stitching through the facing and the seam allowances only, close to the seam, and it is what stops a facing rolling out to the front.

Then try the bodice on, over the bra you measured in. The empire seam should sit level all the way round, 2 to 5 cm under the bust, and it should not cut into the bust or float away from the ribcage.

Step 5: Gather the Skirt

Sew two rows of basting stitches along the top of the skirt, one on the seam line and one 5 mm inside it, and leave long thread tails at both ends. Do not backstitch at either end, or the gathers will not pull.

Pull the bobbin threads from both ends at once and work the gathers along the panel until the skirt matches the bodice width. Gathering from one end only drags the fabric and the gathers end up bunched at one side.

The same arithmetic as a tiered maxi dress, where each tier is gathered to the one above it, applies here. Aim for a 1.5 to 1 gather ratio, so a 60 cm bodice takes a 90 cm skirt panel. Less than that and the skirt will not swing; much more and a crisp cotton will sit out from the body in a shelf. Soft fabrics like rayon and jersey will take a 2 to 1 ratio without a problem.

Spreading the Gathers Evenly

Divide the bodice and the skirt into quarters and mark each point with a pin before you gather. Then gather each quarter to match its own section.

Quarters are the difference between a skirt that hangs evenly and one that is gathered hard at one side seam and flat at the other. Once the pins match, the gathers have nowhere to hide.

Step 6: Join the Skirt to the Bodice

With right sides together, pin the skirt to the bodice at the four quarter marks and then fill in between them, matching raw edges. Stitch on the seam line, between the two rows of basting, with the gathered side up so you can see the fabric going under the needle.

Clip the seam allowance at intervals of about 5 cm so the curve of the underbust seam can relax, then press the seam allowance down towards the skirt, not up into the bodice. Pressing it down is what keeps the bust line smooth.

If you would rather build the dress in panels, a tiered halter dress uses the same gathered joins in a lighter fabric. Finish the seam allowance together with a zigzag or an overlock stitch, and topstitch if your fabric is heavy enough to carry it. On a fine fabric, skip the topstitch and let the seam sit.

Finishing a Curved Empire Seam So It Lies Flat

A curved seam ripples because the outer edge has further to travel than the inner one. The fix is to steam it over a curved surface, a sleeve board or a rolled towel, while it is still damp.

If the seam still wants to fold, run a line of stay tape along the seam allowance before you press it. A narrow strip of fusible tape, applied to the skirt side of the seam, takes the stretch out and the ripple with it.

Step 7: Insert the Zip and Finish the Dress

Sew the centre back seam of the skirt, leaving the zip opening from the underbust down, then sew the centre back bodice seam up to the neckline. Fit the invisible zip with the zip foot so the teeth sit against the fold, and start the stitching at the top of the bodice.

For an invisible zip, press the zip coils open before you pin, and stitch as close to the coils as the foot allows. The zip will disappear into the seam and the pull will sit at the neckline where your hand can reach it.

Then hem the dress. Try it on with the shoes you will wear, mark the hem on the floor or have someone mark it for you, and add 4 cm for the turnings. A narrow double turned hem of 1 cm suits a light fabric; a deeper 2 cm hem gives weight to a full skirt.

Making It Maternity Friendly

The empire line is already the most forgiving waistline for a growing bump, which is why so many maternity patterns use it. Two changes make the same draft work through a pregnancy.

First, cut the front skirt panel wider than the back, so there is 10 to 15 cm of extra fabric to gather over the bump, and gather it into the front bodice only. Second, replace the back zip with a panel of elastic set into the centre back, or a tie, so the bodice can expand.

Leave the side seams at 2 cm rather than 1.5 cm on a maternity version. That extra allowance is enough to let the dress out once or twice before you need a new one.

Fit Fixes for an Empire Bodice

The seam rides up onto the bust. The bodice is too short. Add 2 cm to the bottom edge of the bodice pattern and re-cut, or let out the seam allowance at the empire seam if you allowed more than 1.5 cm.

The armhole gapes. Take a wedge out of the armhole at the shoulder, no more than 1.5 cm, tapering to nothing at the bust. This is the standard fix and it does not change the bust fit.

The back will not lie flat. Usually the bodice is too long between the shoulder and the underbust for your back length. Shorten the pattern at the mid back by the amount it stands away, and the seam will settle.

The skirt stands out from the body. The gathers are too dense for the fabric. Either reduce the gather ratio or switch to a softer fabric; a crisp poplin gathered at 2 to 1 will always stand away.

Frequently Asked Questions

Conclusion

An empire waist dress is a fitted bodice, a gathered skirt and one seam between them, placed 2 to 5 cm under the bust. Measure the underbust in the bra you will wear, draft the bodice to end there, gather the skirt at about 1.5 to 1, and join the two on the seam line. Try the bodice on before the skirt is attached, and the dress will fit.

The seam is the whole design. Everything else, the fabric, the zip and the hem, is ordinary dressmaking that you have done before. If you are about to make one, what fabric have you got in mind, and does it drape or does it hold its shape?
