I purchased my normal American size with this item and it fits beautifully.  I'm a bit taller than average, the bottom hits around mid-thigh in both front and back.  The front drapes nicely to cover my chest or drape to the sides depending on how much of my womanly attributes I need to share with the world. (Typically, none.)

It's sheer enough to be lightweight for summer, yet covers a variety of sins (and carbs) with elegance.  The sleeves hit a three quarter length, with rolled cuffs stitched into place.  From the cuff, it drapes downward, wider than a normal cardigan, but not as long or wide as a traditional kimono jacket so it won't be in the way of normal activity.  There seems to be a slight excess of material where the sleeve ends and the sides are still tucked in - it's a little awkward but doesn't really add bulk to my hips as the fabric is still so light.

I'm very happy with this purchase and will probably look at other colors as well.  Care instructions advise hand wash cold, air dry.
