Very pretty, quite small
This is an attractive, fitted vest. the tight belt on the back gives it a new look, great shape. the fabric is good quality. the neck is tight and high. i usually get a small at retailer, but this small is way too tight and there is no way you could put a sweater under which you usually do in weather cool enough for a vest. judging from the photo, i would guess she is an extra small wearing a small or medium. it looks good with taupe or brown pants/jeans
