Resemblance?

is it just me or do those dresses look dangerously alike?
The first dress is made by Rodarte and worn by Jessica Stam in 2009.
The second dress is made by Valentino and it is part of the Spring 2010 Haute Couture Collection. The design, colors, and even some material are practically identical.
tsk tsk valentino.
