That's just smart recycling. And you shouldn't be penalized for it.
Or, say your flight from Bali was late, and you literally just arrived at LAX, and happened to wear your combination batik bathing-suit/sarong on the plane?
You can absolutely dress that up with your Diamonique jewels and matching sandals, from Duty Free, and should be applauded for your innovative, on-the-spot fashion abilities.
Or the cheerleaders from Glendale South High School mistook you for quarterback Josh Miller's front yard, Friday night before the homecoming game.
I mean, that is not even your fault. And toilet paper is so hard to accessorize.
My point is that there is a lot of pressure to pull off the perfect red carpet look, and hindsight is always 20/20. It's okay to point out fashion mishaps, after the fact - not during the fact.
Or, better yet, before the fact. If Joan & Melissa could come up with a show that filmed them at home with the celebrities, 24 hours before red carpet time, and the celebrities could have several gowns to choose from, and Joan & Melissa could use their criticism in a constructive manner, resulting in the collective best dressed red carpet ever.
