I need your help :)

Hey Whovians,

I'm searching for the Whistles Parka for my Amy Pond cosplay. ( The cosplay is taken from the episode "The Angels Take Manhatten").
But until this miracle will happen I'm searching for a decent ALT.

So I found this:

http://www.houseoffraser.co.uk/Eliza+J+Hooded+parka+coat+with+3/4+sleeves/231429239,default,pd.html?stop_layout=yes

But I am not sure if this parka is a good alternative. The pockets are different, but it has 3/4 sleeves and the colour almost identical. What do you think?
Or does somebody know where I can buy a decent ALT?

Thank you for your help! :)
