All over online marketplaces, blank pocket t-shirts from the 80s and 90s are exploding in popularity for one feature: a hidden "selvedge" edge. You see sellers using the keyword accompanied by pictures of the inside pocket seam all over eBay's sold listings. It seems as though the denim trend is re-manifesting in a smaller way inside the t-shirt world, as buyers are beginning to see this detail as a mark of quality and some comps are going for hundreds. We have even sold quite a few of these shirts ourselves.
What Selvedge Actually Means
Weft and warp direction of woven fabric.
The word selvedge comes from the Middle English "self-edge," meaning "its own edge." The word is quite literally a combination of "self" and "edge." In textiles, it describes a tightly woven, self-finished outer border that prevents fabric from fraying. The phenomenon is traditionally associated with shuttle looms. Before overlock machines could prevent seams from unraveling, fabric needed a finished edge or it would simply come apart.
The Problem
The issue is that the strip visible inside many vintage pocket tees isn't actually the edge of the fabric.
That little strip of white fabric is typically twill tape used to stabilize the material while the pocket is being stitched. Without it, the fabric can become wavy or distorted from the straight stitch.
Why The Myth Spread
The strip honestly just resembles a selvedge edge at first glance. Sooner or later, the market found itself in a feedback loop where sellers repeated the term in their listings and social media accelerated the buzz. Eventually, "selvedge pocket tee" became accepted shorthand and was rarely questioned.

You might be asking: what would a real selvedge look like in a pocket tee, and do true selvedge pocket tees exist?
This is what's interesting. You can find genuine self-finished fabric edges throughout vintage clothing, but they often look nothing like the examples people are familiar with from denim.
Most true selvedge edges match the color of the body fabric. The only way to identify them is to look closely and notice where the weave structure changes. On a pair of twill army pants, for example, the edge of the fabric may appear woven vertically in contrast to the diagonal twill pattern of the rest of the garment.
The reason denim's edge is white instead of matching the body fabric is because it consists primarily of white weft yarns, which are the horizontal threads in the fabric. It's the same reason the reverse side of denim appears lighter in color.
Does It Matter?
The irony is that these vintage pocket tees are still great shirts, whether the detail is a true selvedge edge or not. They're often made in the USA, single-stitched, and built to last.
