Prom Dress


So, I just recently bought my prom dress. I Love the dress but it is a little big in the top like the shoulders and the sleeves. Also, the front is see through which I did not realize. In the picture I am holding the sleeves so it is hard to see how big they really are. My parents do not have the money to get it altered so I need suggestions on how to work with it and fix it.

P.S. Ignore my bra and also the belt because it does not match at all so I decided not to wear it.
