The passage reflects on the fluidity of identity and existence through the lens of consumption and style. The saleslady's comments suggest that if past styles were once part of the self, they can no longer define that self, indicating a transformation over time. This raises a philosophical question: what does it mean for one’s identity to evolve when external influences, like fashion, are consumed and subsequently discarded?

Moreover, it touches on the notion of a "nought," or emptiness, that can absorb various styles, only to leave them void once they are fully experienced. This cycle of consumption implies that while we may adopt styles that shape our identity, they ultimately do not sustain our essence, leading to an existential inquiry about what truly constitutes the self amid perpetual change.
