Hathaway should have worn the Valentino regardless of what Seyfried was wearing. The dresses do not look alike. Besides, the Prada dress sucked.
Seyfried's dress was lavender with a completely different neckline than Hathaway's, which was more of a beige or champagne color.
She should have worn it.
Let. It. Go.
The cut is different, but the color and fabric look so similar at a distance, that they'd have looked very similar in the media.
No actress wants to look like she's dressing the same as the girl who played her daughter.
Time for this bitch to go away!
Yes, given the fact that the two appeared on stage together in a musical number.
If Anne were truly a bitch she would have forced Amanda to change dresses.
Also - the dresses would look different because the women are totally different - tall/short. Brunette/blonde.
