Aspirational: This is what high fashion is supposed to be. No, you're not supposed to wear the clothes you see in the glossy Italian magazines - at least, not with butterfly wings on while climbing a tree in high-heeled boots. You're just supposed to be inspired by, or aspire to, them.
It's fashion as fantasy: This is also the best excuse ever invented by the fashion industry for the politically incorrect things they do.

Use it: We don't want 14-year-old girls to develop anorexia. Surely they can tell the difference between reality and fantasy. This is high fashion. It's aspirational.
