She does not appear to notice!

You watch as the pair continue chatting. Sayza appears so engrossed in telling some tall tale that she hasn't cared to notice her shirt has fallen open, offering a glimpse at her stomach and the curvature of her cleavage.

Your eyes fall on the motes of dust floating across the air. The two woman are conversing beneath an archway, and the sun has risen just far enough above the nearby delapidated appartments for the pair to be hit by bright streaks of sunlight. The contrast between the darkened archway and the sun's rays is stark. Perhaps the bright light in her eyes is preventing the girl from noticing Sayza's wardrobe malfunction, you wonder. Or perhaps she did notice and she prefers the view over giving Sayza a heads-up.
