talking about the dress is unclassy as it takes away from the brilliant skating their competitors showed that day.
By the logic in this and the previous post, every skater who has boot problems and doesn't fix them immediately if not sooner (never mind if they can't) also shows no desire to win, and is as unclassy for so much as breathing a word of it as they hobble off the ice. Or for discussing an on-ice accident that happened in front of the TV cameras, never mind the blood trickling down their face.
I'm sorry for being snippy, but it isn't as if P/C were coming up with a flimsy (choice of word intended) excuse: they knew and WE knew the dress had malfunctioned, it happened in front of the entire skating world!!! Would you rather they said something like "oh nonono, she never even noticed the extra cold place, it didn't affect her mindset in the slightest being exposed, just a normal day at the office." And yes, it's more than likely they have been asked about it in Every. Single. Interview since (were I a journalist, I'd have to bite my tongue right through NOT to ask)
Pretty much every skater in existence has been asked about, and discussed, the factors that impacted on their less than perfect skates. Especially external factors that the entire audience saw doing it (injuries, ice condition). That's what is expected in interviews. So by your reasoning they are pretty much ALL unclassy, including some of your favourites and mine.
