Girls' Generation's Jessica has really cool airport fashion. It’s like her outfits are put together nicely, but at the same time they scream, “I can’t even deal with this flight right now so let me just toss this on and go.” Also when you look at her photos, you’ll notice she really doesn’t have one particular style. It appears she dresses to fit her mood; one day she’s a rock star with leopard print, and the next she’s a kitten in pastel green.
Either way, her style -- whatever it may be -- comes across as effortless and copy friendly. I think anyone would be able to pull off the majority of her looks.
