What separates a good shirt from a cheap one
Look at three things. First, the collar: a decent shirt has a fused or interlined collar that stands without curling after washing, and you can feel the difference immediately between that and a limp single layer. Second, the stitch density: more stitches per inch means seams that do not gape under tension, which is why our side seams are run at a tighter gauge than the market standard. Third, the button placement and the thread: buttons should be cross-stitched and anchored, not tacked with four loose passes. None of this is visible in a photograph, which is exactly why most brands skip it.
