I have literally spent hours on the internet trying to find a good trench. I will not pay 2k for a Burberry just for the "privilege" of...whatever.
Consider: If, like me, you want a trench that is 100% cotton; falls below the knee at least 2-3 inches; possibly has a wool liner, then Grenfell is the ONLY (I really mean it) option. There is no other trench that fits all these requirements. Aquascutums are 65% polyester; others are too short, not stylish enough; too trendy looking; so slim cut you can barely wear a t shirt under it, etc., etc. I ending up 2 years ago buying a Banana Republic 50% cotton/50% polyester "Heritage" trench which is remarkably nice looking and met all my requirements except for the composition. I basically gave up. I wish I'd saved both time and money and just bought the Grenfell. Lesson learned.
