A really warm coat that doesn't make me look like a weeble

[duriandurian]

I am so so cold (been living abroad and UK weather has been a rude shock).
I need a coat. A really warm one.
What would you say is the most stylish/least ridiculous looking long puffa type coat.
Aigle/North Face/ something else?
I like the look of the Aigle Cuckmerry.
But I am 5'7, 10st,1 on BSD so hopeful of soon being 9,10 and slim 12.
Slimmer upper body, chunky thighs.
Any thoughts v gratefully received.
Will also have a rucksack to add to the glamour...

Anyone? Or will I have to buy a comedy shiny ski suit to survive? Already tricked the whole family out in uggs.
Apart from my husband who has spent past couple of years angrily sweating and is now ecstatic to be competing in mud races etc. whilst we hypothermically obserce.

Thanks! I had one before but it does look a little chunky I thought. Last vestiges of vanity before I give in to the desperate need to be warm.
