"Authenticity" doesn't mean much to me. I just want "good", in the sense of well-designed, well-constructed, long-lasting garments. My interest in military clothing stems from that. It's not about macho, playing soldiers, anything militaristic. It's the functionality, the design-solutions, the durability. Likewise workwear.
I think the ambiguity of similarity and difference is very powerful. It's the same scene in different times of year read across the grid, and, of course, different locations reading vertically. But you can get confused and lost in the series. You force the mind, which is always comparing and contrasting, to stumble. . . That ambiguity is very powerful. One is getting lost and refinding oneself.
