Please look at the pictures for this little dress. It appears to be a Japanese style ruffle bottom. This is maybe a size 00 but no size tag to tell please see the measurements they are small. The top part  is gorgeous with the embroidery but it is sheer so you can see thru it.it has a slit from the bodice all the way to the neck but also a button collar. The material, again no tag telling, feels like a rayon. Just look at the pics, measure against your favorite sexy dress and then decide if it will fit. 
Thanks for looking.
