Got it today and all you read on the other reviews are true.  It is a little tight around the arms, so if you have bigger arms, it will be hard to wear.  Also, if you have a "normal" chest area, then it will be a little tight...I actually have to wear a thin bra or no bra because it is so tight.  The length is sexy but not slutty.  I am 130 pounds and 5"6" and I got a small.  If i had time to return it, would have gotten a medium.  I rather adjust down than feel a little tight.  but again, it works.  Finally, the zipper: there is no "zipper-stop" at the bottom, so thanks to other reviews, I did not pull it all the way down and avoided taking the whole zipper out.  I will probably fix it myself before wearing it out.
Overall, cute Halloween custom and excited that my husband got the tom cruise one, so we will be a fun looking team :)
