Broadcloth Shirts Fabric
Broadcloth—very similar to poplin–is a tightly woven fabric with a very simple over-under weave and slight sheen, which makes it very dressy. Broadcloths are great for guys looking for as little texture as possible in their fabrics.
Chambray Shirts Fabric
Chambray is a plain weave fabric. That means it has a similar construction to broadcloth, though it is generally made with heavier yarns for a rugged, blue-collar workwear appeal. Generally there will be white threads running in the weft/width direction such that the fabric has an inconsistent color to it.
Dobby Shirts Fabric
Dobby (which is very similar to Jacquard, although technically different) can vary widely. Some versions are quite similar to broadcloth in terms of thickness and weight, while others can be thicker or woven to almost look like twill.
