It's nice to wake up and find yourself "retconned" into your favorite TV show...especially when you realize you've been mysteriously transformed into a
very recognizable alternate identity. (Arrival at the island can have these kinds of inexplicable effects).
It looks like more than one famous entertainment figure was on that plane...so, with everyone recognizing you, this is your chance to show that there's more to Megan Fox than just being the hottest girl on the planet.
As for how you're dressed...well, nobody can stop you from putting together whatever attire you deem appropriate for the situation, can they? And if the other castaways have strong reactions (including the almost insane jealousy of all the women and the unstoppable lust of all the men) -- and if you yourself find that your outfit has you in a perpetual state of arousal -- who can complain?
ADDITIONAL WARNING: Things may get interesting when the other castaways discover that there's no "Megan Fox" on the plane's manifest. You may have to explain who you really are...and how your transformation seems to be a fulfillment of your forbidden, secret fantasies (and you may even find that some of the
male passengers are envious).
