I've ordered the XS dress for my 4-6 size and it fitted perfectly! I had certain doubts after reading the reviews, but in my case the dress was excatly as short as on the picture provided, and there was no excess fabric under the arms. In fact, I was pleasantly surprised by how it looked on me because usually I don't wear such a sexy clothes :)

But there were also several shortcomings about this dress:

1. It was made of the most cheap and uncomfortable synthetic fibres I've ever seen, so it was not a big pleasure to wear it the whole day. The dress also tried to jump up every time I was walking so I had to stretch it down from time to time.

2. The black collar's fabric was too hard. It wouldn't lay turned down until I sewed it to the dress.

3. The dress itself was made of stretching fabric, but the golden strips of the sleeves were not. I could hardly put my arms in the sleeves because of the strips, and one of they started to tear.

Totally, this is quite a nice dress for one use purpose such as Helloween party. But I wouldn't keep it in my wardrobe to pass it to my daughter some day :)
