I purchased this dress for a family funeral, and it was perfect for my needs. (I ordered the black 3/4 length sleeve dress with the wide v-neck.) I am 55, and the length is just below my knees. I am 114lbs & a size 34B, and the size 4/6 fit perfectly. I would say it is on par with a 0/2 in US sizes. The dress has a zipper in the back, and it has  pockets that blend well with the fabric of the skirt (dont add extra width). The skirt is generous and comfortable, and there are darts on the chest to give it a natural shape. The belt that comes with it is pretty nice (not gaudy or plastic-looking), and it has plenty of holes for waists of all sizes. The fabric has a heavier weight to it, so I did not need a slip, and it was perfect for January temperatures in the NW. I highly recommend this dress as a modest option, and Im sure it would be lovely for more festive occasions as well :)
