This is my first down jacket.  I am 5ft 10 and this fits well for length of the arms.  I bought the XL and it fits Aus size 18 which is US 16.  I can wear sweater and shirt underneath.  I probably wouldnt want it tighter but I would not want it bigger either as it fits really well.  I have 43 inch bust, 46 inch hips and 38 inch waist.  The fabric is lovely and soft and it has a nice satin type finish.  I like the pillow collar, it can be laid down but it looks nice up and is very warm.
