I don't think it's so much being afraid of looking ridiculous as it is that a lot of his couture pieces look like the most uncomfortable thing you could possibly have on, so I'm guessing that there must be some truth to it.
The most uncomfortable pieces are always the best looking lol
I liked Caroline in that dress. She looked good, but it was her stupid looking makeup that let her down.
