Osiris – long sleeve pattern hack

I wear sailor shirts all year long. They are both classy and comfortable and give everyone a chic casual look. From Coco Chanel, to Charlotte Gainsbourg and Brigitte Bardot, all the French icons have worn them. In this article, we give you the instructions for sewing your I AM Osiris tee-shirt with long sleeves.

INSTRUCTIONS

You will need an extra 12 inches of fabric on top of the initial requirements. So it means: 1 7/8 yards of fabric for the top 2 3/16 yards of fabric for the dress.

On the pattern piece of the sleeve (in yellow below), add 10 1/4″ (26cm) to the bottom.

Then, measure 2 3/4″ (7cm) from each side of the sleeve and mark it. Finally, draw a straight line (blue line on the drawing below) between these points and the extremities of the sleeve head. Your pattern piece for the long sleeves of Osiris is now ready to be cut.
