Fix the roof while the sun shines

So, with the hot weather having finally arrived, I, with infinite logic, decided I’d like to get a cold weather coat. Admittedly this decision was also helped by the fact that the Cartwright Parka I already have is more of a spring coat... it is sadly not waterproof!
 
Now getting a big coat obviously isn’t the first thing most people think of in this situation. But it did strike me that as with saying that the best time to fix the roof is when the sun is shining and the best time to buy an umbrella is when the rain is not falling, it might also be a wise move to grab a winter coat when it’s not winter.

Lansdown Parka by Pretty Green

​I appreciate many shops are really not into this, the choice might be limited in the seasonal ranges, but I am open to ideas. Pretty Green have done some exceptional parkas recently. I loved the Lansdown, but I ummed and erred so much at the time that I missed out. 
 
The Kallerton is looking good and there are still some in stock (outside of PG), but I’m not as convinced by it. It seems quite short in length compared to the Lansdown and the hood is annoyingly massive. I don’t want to look like some drug dealer.

​Ideally I want to go off-piste and try and get something similar to the Liam Gallagher Be Here Now version (see above). They really should make those more available. Even PG seem to churn out my faves only in either standard parka green or navy blue and, in exceptional circumstances, some weird colour like white.
 
So... any suggestions for the discerning winter parka buyer?
