Denim fabric guide
Denim Suit Design with AI
A denim suit is a specialist order: ask for rigid denim at 300 to 400 g/m², and expect fewer mills to take it on.
Of the 12 cloths this guide lists for this cut, it sits between ponte di Roma and scuba knit in weight.
Next to ponte di Roma, it is heavier, firmer and less stretchy.

How denim behaves on a suit
In a suit it holds a strong shoulder and a straight front almost without help from the canvas.
Cut short, a structured cloth stands away from the body and gives a graphic, boxy shape.
It is neither warm nor cool, so it works across most of the year.
Wash it cold and inside out to keep the color.
It fades where the body creases, and rigid denim shrinks unless it is sanforised, so the mill's shrinkage figure belongs on the spec sheet.
About denim
Denim is a cotton twill woven with indigo-dyed warp yarns and an undyed weft, which is why it is blue on the face and pale on the back. Its weight, in ounces per square yard, decides how it wears.
Selvedge denim from narrow shuttle looms is a specialist product, made notably in Japan, Italy and the United States; most denim comes from wide looms in Turkey, Pakistan, India and China.
It is almost never lined; seams are flat-felled or bound so the inside looks finished.
Cutting, sewing and color
A 100/16 or 110/18 jeans needle and a heavier thread; flat-felled seams and bar tacks at the stress points.
Indigo is the classic dye, and washes from rinse to bleach change the shade after the garment is sewn.
Its surface is matte, so it photographs evenly under flat light.
