Hemisfèric is a semi-fitted coat that flares at the hips, designed for a B cup and a medium height of 1,65 m (5 ft ).

In this post, we’ll share some tips and advices to adapt the pattern to your body. From taking your measurements to sleeve and bust adjustments or coat length, let’s see together how to proceed to these different modifications.

  • The Hemisfèric coat pattern
  • Kraft or pattern paper
  • Pencils in various colours
  • Tape
  • Scisors
  • A measuring tape
  • A straight ruler and a curved one

The first a important step is to take your measurements. With a measuring tape, take the following measures and compare them to the measurements chart.

  1. The length. The coat length is measured from the base of the neck (the highest point of shoulder) to the hem, passing over the bust.
  2. The bust. Place the measuring tape over the bust, at the apex and make sure the tape is straight in the back.
  3. The waist. To measure the waist, place the tape around your waist where it’s the smallest.
  4. The hips. To measure the hips circumference, place the tape at the widest, about 25 cm (10″) below the waist.
  5. The sleeve length. To measure the sleeve length, place the tape below your arm and measure from the armscye to the wrist with your below slightly bent.
  6. The sleeve width. Place your tape around your biceps at its widest.



Before making any modification, place the waistline (see the illustration) on your pattern. Trace this line perpendicular to the grainline and make sure they are at the same level on all pattern pieces.

We’ll then add the adjustments lines. Trace a new line about 3 cm (1 ¼”) above the waistline to adjust the bust length and another one about 30 cm (12″) below the waistline to modify the coat length.

Once these two lines are made, you’ll be able to shorten/lengthen your coat easily. You can apply this method on almost any given pattern to adjust the length.

Shorten a pattern piece

1 – Choose how many cm/inches you need to remove. Cut your pattern piece along the adjustment line.

2 – Overlay the two pieces the number of cm/inches you want to remove. Make sure the grainline is straight.

3 – Tape the pieces together.

4 – Redraw the pattern shape.

Lengthen a pattern piece

1 – Cut your pattern piece along the adjustment line.

2 – Place a piece of kraft or pattern paper under the two new pieces. Decide how many cm/inches you need to add and spread the two pieces apart accordingly. Make sure the grainline is straight.

3 – tape the pieces to the kraft/pattern paper and redraw the new lines.



It’s rather easy to modify a raglan sleeve and adapt it to your arm or shoulder width. Here are some modifications that can be useful.


Reduce the sleeve width

If you have small arms or you want a more fitted sleeve, you can reduce the width on the upper seam of your front and back sleeve pieces, drawing a new line between the top and bottom notches.

Increase the sleeve width

If the sleeve width seems too tight, you can increase the width over the upper edge of the front and back sleeves like we did to reduce it.

Shorten the sleeve

As for the coat length, you need to determine how many cm/inches you need to take off the total length of the sleeve. Cut the sleeve along the adjustment line and overlay the two pieces the number of cm/inches needed. Tape the pieces together, make sure the grainline is straight and redraw the sleeve edges.

Lengthen the sleeve

As for the coat, cut your pattern piece along the adjustment line and spread the pieces apart the number of cm/inches you need to add. Tape to a kraft paper and make sure the grainline is straight. Redraw the pieces if necessary.

Widen the shoulders

If you have broad shoulders, you don’t want your coat to pull when you move your arms. You need to add some ease at the shoulder edge, on the upper seam of your front and back sleeve pieces.

Reduce the shoulders

If you have small shoulders, you need to reduce the shoulder curve of the front and back sleeves.

These adjustments are easy to make and will help you get the best fit possible for your Hemisfèric coat!

Hi Pauline, how shall I adjust the waist part if my bust is size 42, waist size 44?

Hi Rachel, you can blend the sizes from the bust to the waist for each pattern piece.

Hello, I am having a lot of trouble working out how to do a fba on this pattern. I have marked the waistline and am attempting to splice and spread to add room but the unique shape of the pattern piece and darts are confusing me. All the tutorials I can find online show basic bodice pieces and I can’t find one using raglan sleeves and princess seams. Can you please provide guidance here? I’m sure this is a common adjustment and others may also appreciate the help. Thank you.
