This is one of a selection of superb printed denim chambray fabrics. if it helps, they weigh 125 grams per m² approx 4oz denim shirting.
In real terms this fabric will make shirts, lightweight summer shorts, dresses and not the skin tight variety but A-line skirts is a go.
100% cotton and lovely and soft, it will make something you can wear time and time again.
This 4oz Denim is a classic as they come, in a traditional but very pretty small scale floral in a white overprint on a dark blue denim chambray.
