Fashionably late

I don't understand why fashion people are always late. Isn't fashion about things that go in and out of style. So shouldn't being late have gone out of fashion at some point? "Why did I show up 8 hours early for your party? I was just in Paris and it's the next big thing. You'll understand when you see next month's Vogue."

Besides, fashion people love things that are difficult...high heels, corsets, etc. Well nothing's harder than being on time. C'mon fashionistas, just call it being "fashionably prompt" and let the suffering begin!
