I loved this costume!  I did get the petticoat and it was super fluffy, but still looked really cute.  I felt sexy but not overly revealing.  I'm 5'4" and 124lbs and a 34D.  I ordered a small and it was snug around my ribcage, so I probably could have gotten away with a medium.  I was very pleased with the quality of the material and felt it was money well spent.  Some Halloween costumes are cheaply made, but not this.  I got a lot of compliments on the outfit!  Overall, I am very happy with it.
