What shape/style is this coat?

[Winterjoy]

I'm looking for a coat in this exact shape (smallish lapels, single button etc) but in bottle green. Trying to narrow down the Google results is proving difficult - does this shape/style have a name?

Single breasted cocoon.

I would look at Boden and Whistles, they seem to have similar styles and Bottle Green, well any kind of green is in this year.
Bouclè looks good for this style also.

It’s a cocoon shape darling xx

Or a 'flowing trench coat' 😬

Or even a 'boyfriend' coat!
