Well there’s well made items that have high resale value, and there’s ones that don’t, but they’ll add to your closet.

If you want to resell items, look out for Carhartt. If you just want nice clothes for yourself, then Eddie Bauer.

I think for clothing, it’s good to get a sense for materials. Such as wool, cashmere, angora, etc.

And then of course there’s grades of fabric, so anything that drapes nice, doesn’t wrinkle easily, and has some thickness.

And then there’s the purpose of the garment—does it seem made to a specific function? Does the fabric make sense for that function? Do the features work for their purpose?

One thing that seems a mark of good quality is YKK zippers.
