Purchased a size small for my daughter who is 11 1/2 for her valentine dance at school.  Popular dresses in style now are super super short, and since my daughter is a bit of a tomboy and doesnt normally wear dresses, she did not want anything that she wouldnt be comfortable in (ex: cant bend over or dance in without flashing folks).  We shopped on here and she fell in love with this dress and the print!  (roses with black polka dots). I have to admit I loved the style too...very retro! The price was great, so we decided to get it.  She probably could have fit into the extra small, but we played it safe and got the small.  She loved the dress and got many compliments on it....one boy even told her she looked beautiful  :)  We are going on a cruise in a few months so this will be perfect for one of the formal nights....we didn't purchase the petticoat, but I might get it for the cruise.  It looked cute without it though.  Well made and pretty dress!  What a deal!
