Korean Nida Material with chiffon Dupatta.
Kaftans are long, lightweight dresses that hang loose on the body. They're like long-sleeved tunics but tend to have wider sleeves and are made from lighter fabrics.
The Flowy fabric it is usually made of can make your dress look inappropriate for the occasion you want it unless you upgrade its look with carefully selected accessories. Having said that, a kaftan made of silk, cotton or another natural fabric is definitely a great pick for a casual outing.
