I am 5'2 and 106 lbs.
I bought the Club Monaco Keren blazer in 00. It is wool in a houndstooth pattern with leather buttons. The sleeves are a good length and the blazer is tapered at the waist and the length hits me near the hip bone.
A photo of me in the blazer is here: http://thatsaprettyhat.blogspot.com/201 ... -chic.html
