Very roomy everywhere except the arms which feel a little restricting in comparison with the rest of the coat. The sides are all open with just popper fastenings, the poppers had a tendency to open so I stitched the sides up (which was easy, I am a seamstress). I love the fabric, it's quite a lightweight quilting and definitely shower proof. The style is lovely, like a big cape type coat you can pop on over large jumpers. The length is quite long which I love and the hood is great. Very easy to wear. Love it.
