I have just received a Burburry trench coat. I'm not as confident in the sizing as I was when I ordered it. I'm a 42R [at Marks and Spencer anyway] and the coat is available in a 41 or a 43 inch chest measurement - so I went for a 43. Can trench coats be tailored readily? If anyone has had adjustments made to theirs I'd be grateful to hear about it. If I could choose I't want it slimmed a little and shortened by a couple of inches - I'm 6ft and a smidge and pretty chunky, and the coat covers my knees [just]. My assumption is that with a suit a 41 would probably look silly, so it is better to be slightly too large than too small? Trench in question: M.
