As usual nobody tried something exciting except Zoe Saldana and Diane Kruger but I feel their effort didn't produce anything breathtaking.
In the case of Zoe Saldana I feel there is too much going on... I don't really like the tie-dye effect on dress, especially on occasions others than going to the beach. Just add the glittery bust and, wow it's just an overall mess.
I don't like the divisions on Diane Kruger's Chanel Couture dress... Plus the ruffles in the middle give an overall look of french cancan, not very appropriate for the Oscars...
My favorite looks
