I bought the dark blue Anthropologie 'Elevenses' Ruffled Trench coat in size 0 at their SOHO store in September 2012. It hits at the mid-thigh and is a great coat for mild weather. It is self tied and has plenty of pockets. The ruffle looks so sweet and balances the military look of the double buttons.
I am 5'2 and 109 lbs. I wear a size 00 on top and a 2 on the bottom.
The coat is at the Anthropologie website here: http://www.anthropologie.com/anthro/pro ... 121054.jsp
