I wear a Small in most tops (37 bust, 29 waist, 38 hips) and I usually buy 8 Tall in regular JCrew jackets but read that this coat runs large so I ordered 6T. Oh my goodness!!! It was HUGE! I would have to order the 2T but I’m worried that even sizing down another 2 sizes would still not be enough. There was a good 10” width of extra room when buttoning it. The fabric is very nice and soft and it’s well constructed, but this is not just oversized…..it’s way, way over the top on having a “relaxed fit”. Instead of looking like I was wearing a nicely made coat, it looked like I was wearing something way too big for me from a donation bin.
