An unstitched 3-piece lawn suit typically consists of three separate fabric pieces that you can stitch into a custom outfit, usually a traditional dress like a kurta, shalwar, or dupatta. These are especially popular in South Asian countries, like Pakistan and India, and are made from light, breathable lawn fabric, which is perfect for hot weather.

A typical unstitched 3-piece lawn suit includes:

1. Shirt Fabric (Top): This is the fabric for the shirt or kurta. It can come in a variety of designs, such as embroidered, printed, or plain.

2. Trouser/Salwar Fabric: This piece is for the lower portion of the outfit, such as trousers, churidar, or salwar, depending on the style you choose.

3. Dupatta: The third piece is a matching or complementary dupatta (scarf). It can also be printed or plain, depending on the design.

These suits are sold in fabric form, and the customer has the freedom to take them to a tailor to stitch them according to their own measurements and style preferences. It allows for more customization than buying a ready-made suit.
