I had to go a size up but expected this from Next, am usually a 10-12 with relatively broad shoulders so ordered a 14. Coat fits brilliantly across the shoulders and arms. I am planning to take about 8 Inches off the bottom though as it’s much longer than I want; I’m 5’7” and if I keep it the normal length the bottom would get muddy and torn as it would be very easy for me to scuff the back with my shoes as the jacket goes far past my knees, that’s just my preference though. No other problems! Huge pockets!
