I’m guessing the six P to eight P would fit okay. What dress size are you?

Here is a link to a great JPG that has helped me with coats for family members this holiday:

.(For women) based on height: http://tinyurl.com/q577d2a.
And, there is also a great chart for measuring all of the jacket for the right fit : http://tinyurl.com/pak29hj

Also, you can Google coats size charts under images for many others…even ones that take into account what height shoes you may often wear.

(BTW as someone who is 5’5 and very thin too, I have found that keeping coats to the mid of my knee , at most, keeps me from looking either “swimming” or “sticked legged”)

Hope it helps…good luck on finding that perfect coat!

Peace2u!
