I agree about the detailing.
But the color is tricky. In the U.S., the color yellow has negative associations ("yellow-bellied"), although envy and jealousy are more green than yellow. Throughout Asia (Asian posters please correct this if I am wrong

), and especially in China, yellow is a very positive color signifying good luck, heath, wealth and royalty. (If your name is Huang, Wong, etc., you are Mr. or Ms. Yellow.)
I don't think there is any association of the color yellow with sadness, regret, etc., which are the focus of Send in the Clowns. So in this case, although Yuna was never lovelier

, I don't think that the dress served the program as well as blue or violet would have.
Or for that matter, this. Come on, give it a chance. "Isn't it rich?…"
