[Module 7] Draping | 5. Draping Intermediate - Draping Approach, Part Two

In this second part to the Unit let’s think a little summery as a theme to the next two garments which both cover slightly different aspects to intermediate draping.

Bias Flirty Dress

A simple above the knee bias flirty swing dress with a high neckline. Although there are many options you could use for a neckline for this dress.

This is a quick to drape dress with little shaping after the bust. This one is a great choice to show off a larger print, think 1960’s vintage! Here is a quick sketch to get an idea of silhouette.

There are no waist darts (the lines in the sketch just indicate how the fabric drapes and flows) and you can see the effect of this release of fabric over the bust which falls down to add to the flare in the front. The amount of flare you add to the skirt is personal choice and to some extent is determined during draping and is positively affected by the size of the bust in the front. The complexity is getting the right amount of flare in the Back to balance the Front especially if the Bust is on the larger size.

The armholes are cut in a little to emulate a jewel neckline and the shape is slightly razor back in the Back as the armholes come in a little. The length of this sample is above the knee but you could go higher even to a mini if you dare as the neckline is high it’s going to look sexy with a shorter skirt.

As this is a fit and flare it will skim over any belly area so it is comfortable to wear and also forgiving to wear so great for a summers day. As there are minimal darts and seams with a flowy skirt this dress would be ideal to show off a beautiful printed fabric. Think smaller print from a smaller person go bigger with the print the larger the person, it is all about proportion.

The Neckline in this example is high as per the Base Template and you can make it into a more Flexible Pattern by adding collars to it, Auxiliary Reference Information - Draping – Collars gives you half a dozen collar options to draft that will go with this dress so it is worth working through this mini class in conjunction with looking at draping this little dress.

Other design options would be to design a neck and spaghetti straps or a high round neck and wider shoulder seams, or boat neckline or halter neckline. You could create a full Flexible Pattern pack here by swapping in all of these different necklines if this is the type of dress you love to wear.

Prepare the Muslin

Measure the desired length of the dress from neckline to base in the back and add on another 12” and tear off the piece using full fabric width.

We are draping the fabric on the Bias Grainline which means that when you turn your muslin 45 degrees onto the bias it will be something like a diamond shape so you do loose width at the top. It is important then that you will need to ensure that you have enough width at the top to cover you shoulder area when you hold the fabric up especially if you are draping the fabric as one piece across the full Front of the Body Form. It might be worth a quick check to ensure that you have enough fabric before you make your cut.

Tear off the selvage edge if you need to (sometimes the selvage pulls the fabric tight) and press and square the fabric. Initially mark on a Straight Grainline from the selvage edge, then mark your Bias line 45 degrees off this line. To differentiate between the two Grainlines mark a double line for Bias Grainline and mark it as long as you can on the muslin.

Repeat this process so that you have another piece for the Back.

Solely in the interests of saving tape and less waste we are not going to use tape to mark seamlines and Style Lines we are simply going to rely on the Guideline on the Body Form to guide us. If you prefer to use tape mark on your Centre Front, the Neckline Front and Back, Bust Line Front and Back and Armholes, Shoulder Line, and a couple of inches for the start of the side seam.

Ensuring you have enough fabric in width at the base for when you mark the hemline, you may not have enough fabric at the sides in the base to come down to the same level but don’t worry we will resolve this during patterning, or you can pin on fabric if you prefer.


Lifting the fabric to give you enough for the shoulders pin at the Neckline Centre Front. In this example the Neckline for the Base Template is used as a guide to create a high neckline because we will be looking at draping collars for this demonstration.

Feel though to the Body Form and determine where the Bust line is mark in pen at the centre Front at this point and remove the fabric.

Extend this mark perpendicular to the bias line across the fabric. This is going to help keep the grain straight as you drape the fabric.

Re pin the fabric onto the Body Form at the Bust Line/Centre Front and pin back up to the Neckline at Centre Front.

Choose a side to pin out and smooth the fabric out to the side pinning along the Bust Line Guideline you have drawn ensuring it is level to the Guideline on the Body Form.

Smooth from Centre Front across the top bust area to the Armhole and start pining this out moving down as you go if you did not use tape you will need to feel for the edge of the armhole on the current Base Template outline. Go down as far as you can smoothing as you go and a Dart will naturally start to form.

Pin up the side seam and pinch out the Dart and pin it in place. If you are using a knit fabric to do your draping you can tug a little here and manipulate the fabric to stretch over the bust and eradicating the need for a dart in the armhole but again this depends on the size of the bust. Trim and snip into the armhole to relax the fabric.

Smooth, trim across the Shoulder from the Armhole and you will see that tension in the fabric starts to build up in the Neckline.

Start smoothing across to the Neckline and start trimming and snipping into it. Hold up the Neckline so that you don’t trim down too far.

Here it is with a little more trimming and snipping, I always under trim to start with letting everything settle each time.

Eventually getting everything under control.

Now you will notice that although we have fabric covering the full front we have only pinned half of the body form. When draping fabric on the bias it will stretch and we don’t want it to stretch out too much while we are working with it. So it is helpful to keep the fabric across the full front body to support the bias stretch for the side that is being pinned. It can be cut away later. Or just cut it off if you don’t feel you need it.

Mark all of the seamlines pinned out so far, Neckline, Shoulder, Centre Front and Side Seam pinned so far down to the Bust Line.

The red line shows the new position of the Armhole, around 1” down from the current position of the Base Template and 1” in at the Shoulder. The Armhole is redrawn.

Re pin, trim and clip to any new seam positions. Also mark out the Dart.

The skirt portion has some volume so it is difficult to define the side seam for the front at this stage without having a back piece to pin to so before defining the side seam we drape the Back in the same way as the Front.

As with the Front mark the Bust Line and pin in place up to the Back Neckline on the Centre Back. Smooth across the Back along the Bust Line and pin in place across to the Armhole, pin the side from the Bust Line upwards to the Armhole. Smooth up to the Neckline and out to the Armhole and pin and pin the shoulder in place trimming and snipping as you go. You may need to unpin some of the Front to get accurate pinning on the shared seamlines.

When everything is pinned, trimmed and snipped then mark out the Armhole leading through from the Front in Base Armhole and Shoulder Seam.

Fold over the Front Shoulder Seam on top of the Back Shoulder Seam to tidy it up a little in that area.

Trim the sides on both Front and Back from Base Armhole down to the Bust Line and pin together the Back and Front Side Seam to the outside. It’s looking a little abnormal at this stage but just go with it for now. The dress is fitted somewhat to the Bust Line then the flare will start.

Next comes the creative but tricky part of assessing the drape of the skirt in Front and Back and joining the Side Seam.

With a large bust you are going to end up with lots of volume in the front as the fabric is released and falls over the Bust, but this volume will not be matched in the Back. On a very large bust this can be a proportional issue causing the front to look so much bigger than the Back. One way to deal with this is to create a jump pleat or two in the Back to draw up and release a little extra fabric and release it into the skirt, when creating the A-Line Skirt above we looked at pinching out a little extra fabric to create more volume, so have a play with how much you would need to pinch out to balance things in the side. If you want to do this pin the Centre Back to hold it in position and pinch out some fabric at the Waist as you would with a Waist dart and pin it upwards going to nothing around or just under the Bust Line. This will take a certain amount of experimentation and standing back and looking at the proportion until you are happy with the result.

How much flare to add for the skirt? Well it really comes down to personal choice and a little experimentation.

If you pin down what you have in total then you are going to create perhaps too much volume in the sides can you see how this creates a diamond shape in the side.

If you have too much fabric you will not be able to clearly see the shape you want to achieve so it is a matter of trimming fabric down a little until you get closer to the desired look. But do this a little at a time don’t trim away too much.

So pin trim and stand back and view from all angles.

Here you can see how the Back has been pinned to create extra volume in an attempt to balance volume in the Front and the Back. This could be sewn as a dart or Tuck or just left to hang freely.

If you place the fabric for the back under the front fabric at the side and just let everything fall down you will start to see the volume that is being created, actually this dress has a little more volume than these photos suggest.
