1  Find your height along the vertical line on the left of the chart.

2  Find your weight along the horizontal line at the bottom of the chart.

3  Where they intersect on the chart indicates your size. If the intersection is at a curved line, size up or down based on your preference for a more snug or looser fit.

How It Works: Custom Shearling

Since we produce each SILJA Shearling Jacket one at a time, we are able to customize the fit just for you. Select your normal size, “Add to Cart” and a pop up window will appear. You will then need to provide the required measurements (see below) for a bespoke fit. Please note, all custom orders are final sale.


  • Height
    Feet and inches or cm will do

  • Weight
    Lbs. or Kgs.

  • Bust
    TIP: Wrap a soft tape measure around your bust. Take it around your back, across your shoulder blades and under your arms. It should wrap around the fullest part of your bust. The tape should be straight and parallel with the floor.

  • Hips
    TIP: Wrap the tape measure around the fullest part of your hips and buttocks. Keep the tape measure parallel to the floor.

  • Arm Length
    TIP: Measure from the shoulder point to the tip of the thumb.
