Cotton fabric guide
Cotton Blazer Design with AI
Mills make cotton blazers regularly, usually in cotton twill at 220 to 300 g/m².
Of the 12 cloths this guide lists for this cut, it sits between duchess satin and suiting linen in weight.
Next to suiting linen, it is more fluid and warmer to wear.

How cotton behaves on a blazer
In a blazer it takes interfacing and pressing evenly, so a classic tailored line comes out clean.
At this length a medium-weight cloth hangs straight and moves a little at the hem.
It is neither warm nor cool, so it works across most of the year.
Care is simple: a machine wash at 30 to 40 °C.
It creases moderately and can shrink by a few percent unless the cloth was pre-shrunk, so ask the mill whether it was.
About cotton
Cotton is a plant fibre spun into everything from fine poplin to heavy canvas. It breathes, absorbs moisture and softens with each wash, which is why it is the default cloth for everyday clothing.
Long-staple cottons such as Egyptian or Pima give a smoother, stronger cloth; organic and recycled cottons are widely available at a premium.
It rarely needs a lining, though a light cotton is lined or faced when a pale color would show what is underneath.
Cutting, sewing and color
Sew it with a universal 80/12 needle; flat-felled or overlocked seams both hold, and it presses well with steam.
It takes reactive dyes readily, so solid colors and prints both stay true after washing.
Its surface is matte, so it photographs evenly under flat light.
