I don't know who the costume designer for ALIAS is, (okay — wait, thanks to Google, now I do. Laura Goldsmith). Anyway, Laura needs to take a look at the Spring 2006 Gaultier couture collection, because doesn't this dress look like Sydney Bristow is about to open up a giant-economy-size can of whup-ass on some baddie? Preferably just seconds after picking up a champagne flute?
Actually, now that I look at it again, perhaps it is not quite tight enough or garish enough or made of enough pleather to qualify as an "undercover" outfit on ALIAS. Although it's certainly eyecatching enough.)
It's certainly an interesting confluence. So many of the high-fashion collections seemed to be aimed at amazingly-fit superspies, yet so few of us actually ARE amazingly-fit superspies! Luckily, amazingly-fit superspies seem to need a LOT of changes of clothing.
