What style/colour coat with these boots?

[StrawberryLipstickStateOfMind]

Tempted by these topshop boots for all year round but could do with another coat too.

I currently have a black cargo biker from all saints and a charcoal grey fitted military style coat... I was thinking a more casual cocoon style coat might look better with these though... just wasn't sure on colour either?

If anyone would like to do some fantasy shopping for a coat that would look good with these boots I'd be very grateful! Around £50 or just over in sales would be ideal!

I would pair them with something like this (Mango)

Thanks @CrotchBurn

I went for this in the end- topshop too, like the boots- so very similar to your suggestion.

Quite pleased with that- coat and boots for £80
