Belcarra blouse adjustment: broadening the shoulders

When I made a toile of the Sewaholic Belcarra Blouse the fit was pretty good, the only niggle I had was that it felt too tight across the shoulders – it was a bit uncomfortable when moving my arms and the neckline was being pulled wider.

Here’s how I adjusted the shoulders: (note – I don’t know if this is the “correct” way to do this kind of adjustment, but I was happy with the results (see my first finished Belcarra here) so thought I’d share in case it is useful to anyone else)

In the pictures, the blue pen shows the markings traced from the pattern, the red pen shows the adjustments.

  • Measure 1.5cm (the seam allowance) in around the corner of the seam that connects to the blouse front (or back – you need to adjust both shoulder pieces) and the underarm seam, mark point A where the stitching lines here meet
  • Draw a line from the centre of the shoulder seam notch going through point A, to the edge

  • Cut along this line from each edge towards point A, do not cut all the way along – you want to leave point A as a pivot point
  • Tape one side of the cut edge to some additional paper (I’ve just used standard tracing paper)
  • At the shoulder seam, measure from the edge of your taped down side and mark a short line B to indicate how much you want to lengthen the shoulder seam by (I lengthened by 1.5cm)

  • Pivot the free side such that the shoulder seam meets line B and tape in place

  • You’ll see that the shoulder seam now has a step where you’ve broken the line. Fix this by using a French curve or go free hand to draw a new line from the lower part of the sleeve to the neckline. (You have now both lengthened the shoulder and added a bit of extra width)
  • Make sure your notch is clearly visible

  • If you are making view A or C of the blouse, that’s it, you just need to cut out your new shoulder piece and repeat these steps on the back shoulder
  • If you are making view B, extend the tuck lines to the edge of the piece so that you have straight lines again. Repeat adjustments on back shoulder

Do you know of a different, perhaps better, way to adjust raglan sleeves for broader shoulders?
