back around 2002 I had some T shirts from the Gap (so, pretty mainstream) that had the visible stitching and tags look like the shirt was inside out; sort of a duplicate in that if you actually wore them inside out they still looked inside out. the only way to really tell was the little washing instructions tag on the inside.

i really liked them, was sad when they went away

They are. Lots of sweaters with seams on the outside.

I'm talking actually taking clothes not crafted to be worn inside-out.

Take your favorite pair of pants with seams and put them on inside out. Favorite button-down or polo, etc.
