Ladies, This is my first time to wear a formal dress. I am so nervous, but also excited. I will have a semi formal party at Friday. And I need your help to find a perfect dress. I want a dress can cover my "big arms" and back. But short enough to show my leg and boobs My budget would be less then $150 since I might just wear them once. I am a college student, 21 year old. This is our gala. to celebrate college graduation. Please let me know what website would have that. I am truly appreciate any of your input. I need the dress here on Friday. Thank you all.
