A while back I posted the basic bodice pattern -tutorial. That one was with darts. So now this pattern should be easy.

The Dartless Bodice Block is useful when you want to draft loose fitting garments. If you have never drafted a bodice pattern, this is a great way to start. I included instructions on how to draft the sleeve, too.

You’ll see that the instructions are quite similar to the other basic bodice pattern, just more simple.

I’m continuing with the metric system.

The Measurements Needed

Here are the measurements you will need to draft the dartless bodice pattern. It’s the same picture of the industrial size M -measurements as last time. The horizontal measurements are already divided in half.

You can find instructions for taking the measurements in the Body measurement -chart of mine. Just sign up with the form you find here at my website if you look at the side panel, or at the bottom of the page if you’re on mobile.

Dartless Bodice pattern: starting point

Doesn’t this rectangle look familiar, too? Well, it’s pretty much the same as last time. There’s just more ease in this pattern, because we’re going for a loose fit.

So the height is your back waist/nape to waist length+ 2cm. The width is ½ bust circumfrence + 6cm of ease.

To separate the little back neckline -rectangle at the upper right corner, the height is 2cm. For the width, choose your measurement among these:

  • Size XS: 6,5cm
  • S: 7cm
  • M: 7cm
  • L: 7,5cm
  • XL: 8cm

Then draw the horizontal line in the middle using your armscye depth -measurement + 2cm of ease. This will be the underarm line.

So using the size M measurements: 20cm+2cm = 22cm.

Mark the side seam position exactly in the middle of the underarm line.

How about the 2 vertical lines on both sides? For the back side calculate ½ back width + 2cm of ease.

Using the example measurements: 18cm +2cm = 20cm.

For the front side it’s ½ chest width + 2cm of ease.

So here it’s 17cm +2cm =19cm.

Dartless Bodice Pattern: Back

Now it’s time for the details, starting from the back piece. There are numbers to make it easier to follow the instructions.

1. Draw the neckline. At least the first 3 cm from the c.back should be a completely straight line and then you can curve it.

2. Measure 4 cm from the top and draw a short parallel line. This will be the guideline for the shoulder slope. Then calculate your shoulder width + 1 cm of ease (because we want the whole bodice to have a similar kind of loose fit) and draw a line starting from the base of neck and ending on the guideline you drew earlier.

3. To draft the armscye, first measure 5cm upwards from the underarm line (=point A). And then mark point B in the middle of the shoulder tip and point A. These are your guide marks for the armscye and at the same time will be useful notches later for a sleeve.

The armscye line should touch the point B, but stay about 0,5cm outside of point A. Don’t curve too much here.

4. At this point we can also add the hipline. So check your measurement chart for the distance between waist and hip.

5. To finish the back piece, we need to draft the side seam. Just measure ½ hip circumference /2 + 2,5cm of ease along the hipline.

For example 48cm / 2= 24cm + 2,5cm = 26,5cm.

Draw a line between this point and the reference point you have in the middle of the underarm line. Then you can just check there’s enough room for the waist, but that shouldn’t be a problem anyways.

Dartless Bodice Pattern: Front

Now that the back piece is ready we can draft the front piece.

1. Starting from the neckline. You can get the A-B distance from the back piece; The front neckline width is the same as back.

Add 1 cm to that to get the missing measurement from point A downwards. Now you can draw the front neckline.

2. Next up, the shoulder slope. The procedure is identical to that of the back piece. So measure 4 cm from the top and draw a short parallel line ( =the guideline for the shoulder slope). And then draw a line starting from the base of neck and ending on the guideline. The measurement should be exactly the same as that of your back shoulder.

3. Although this pattern doesn’t have a bust dart, it will be useful to mark the bust point on the pattern: Measure the bust level from point A downwards. Mark it at the c. front and from there, measure ½ distance between bust points. For the sake of the loose fit, you can even add 0,5cm of ease. Mark the bust point here with an x or a circle.

4. To draw the armscye, let’s first add a guide mark 5 cm upwards from the underarm line. The front armscye line should touch this point. You can curve it more than the back armscye at the underarm region. Make a nice continuous line from front to back.

5. Measure ½ hip circumference + 2,5cm of ease.

For example 48cm /2 = 24cm + 2,5cm = 26,5cm.

And draw the side seam uniting the two reference points at the underarm line and hipline.

Extra:

Sometimes you’ll need to use this pattern only from the waistline up. You might notice that it’s too short in the front. To correct this, you can draw the front waistline a bit lower using your front waist measurement.

Measure the front waist length from point A downwards and draw a second waistline. After the bust point width, you can unite the line to the regular waistline, curving it a bit.

So now your Dartless Bodice Block is ready and we can draft the sleeve.

The Sleeve for Dartless Bodice Block

To draft the sleeve pattern, we will need some measurements from the bodice. Other than those, you should have the total sleeve length and the elbow level measurements handy.

Here’s the bodice we just drafted. I marked the areas we need to measure to draft the sleeve.

The Sleeve Cap

1. Start the pattern by drawing these 3 horizontal lines. The first two are 5 cm apart from each other. To draw the uppermost line, measure the distance between the underarm line and the shoulder tip of your bodice (1) with a straight line. *Detract the following cm (=x) from the measurement :

  • Size XS: 3,5 cm
  • S: 3,5 cm
  • M: 3,5 cm
  • L: 4 cm
  • XL: 4cm

For example, my bodice size is M, so I’d detract 3,5 cm.

2. Then mark the starting point for the sleeve cap along the future bicep line. Measure the bit 2A from the bodice and add 1 cm. From that point, draw a vertical line straight up to the second horizontal line.

The next measurement is that between the armhole notch and the shoulder point of the bodice front (3), measured in a straight line. Add 1 cm of ease.

Draw a slanted line using this measurement ending on the uppermost guideline.

Then do the same with the bodice back (4). This time the line goes in the other direction and ends on the second guideline.

Draw a vertical line straight down from that point. Then measure the bit 2B from the bodice and mark the end point of the sleeve along the bicep line.

3. Now we have this house-shaped sleeve cap. Mark the middle point along the two slanted lines (=reference points). Then draw your sleeve cap as in the picture.

The front armhole line should start with a more pronounced curve on the bicep line.

Use the reference points to shape the upper part of the sleeve cap; at these points, the curve should be at its maximum, about 1,5-2cm away from the slanted line. The front side is usually more round than the back side.

Notice where I placed the sleeve armhole notches: 5 cm above the bicep line, just like the bodice has its armhole notches 5 cm above the underarm line.

Sleeve Cap -check

Compare the measurements of the sleeve cap and the armscye lines of the bodice, on both sides of the armhole notches. The basic sleeve has about 10% of ease between the cap notch and the armhole notch, both front and back. Meaning the sleeve cap is bigger than the armhole of the bodice.

So measure the armscye line length of the bodice between the armhole notch and the shoulder tip, and add 10% to get the measurement needed for the sleeve cap. For example if the measurement is 13cm, the ease would be 1,3cm and as a result, the sleeve cap should measure 14,3cm.

If you’re not happy with the measurements, try to adjust the sleeve cap shape. You can modify the cap width and -height. And also move the cap notch a bit left or right if you need to distribute the ease.

The remaining part of the sleeve cap, after the armhole notch, should have the same measurement as the bodice. You can adjust the sleeve size if needed.

Rest of the Sleeve

When you’ve controlled and adjusted the sleeve cap, mark the middle of the bicep line and draw a line straight down from that point. This will be the grainline of your sleeve pattern. It doesn’t always coincide with the cap notch btw.

Measure the total length of your sleeve starting from the top of the sleeve cap and choose the hemline width. It could be for example 30 cm this being a loose fit garment, so divide 15 cm on both sides of the centre line. Then draw the underseams and finally the elbow line.

All the Pattern Pieces

Here are all the pattern pieces of the dartless bodice block:

Now, if you followed my other bodice pattern tutorial, you know the drill: copy the pattern. Never cut the original. Check all the lines. They should continue smoothly between the front- and back pieces (armscye, neckline, hemline..) The waistlines should match.

Toile

Make a toile to check the fit so you can make corrections to your original pattern. Besides the general fit all around, you will want to check for example the shoulder seam position and if you managed to get the bust points right.

If you prefer, you can also check the bodice pattern without the sleeves first, before even drafting the sleeve pattern. So that if you have something to correct around the armscye line, or the side seam, you have less things to correct when the sleeve doesn’t exist yet.

Especially when there are no sleeves attached, the dartless bodice will have some extra volume at the front armhole-area. To get rid of it, you can make a little dart towards the bust point. Afterwards you can rotate the dart in another direction or turn it into more flare at the hemline.

Once you’re happy with the result, the dartless bodice block is ready for use.

Here’s a summary on the dartless bodice pattern construction. If you’re already on my mailing list, I have sent you the link.
