I'm a size 50 jacket, and I have been looking for a smoking jacket for years. Vintage sizes that big are rare. I drool over the ninedeep ones and will probably break down and order one at some point, but I bought this one last month and it is perfect. It is not too light or heavy, the classic design and seems like it will wear for a long time. I am not associated with the vendor in anyway, but it is so damn hard to find this thing I thought I should share.
