Doubts about Prom Dress

So I went to shop for a prom dress and found one that I really like but it was $500. I’ll post a picture of it anyways cuz it was gorgeous (ignore my weird facial expression)

So then I kept looking and found this other really cute one that was only $250

And so I decided I’d get it and put down a $50 deposit to put it on hold. I just don’t know if I made the right decision. Does it look good on me?

(P.S. here’s last years dress. I was trying to go a little bolder this year but I feel like I still went kinda simple)

Thanks in advance!

UPDATE

I went shopping some more today and found this one

I’m thinking of maybe getting it in a navy blue color just so it’s not too similar to last years and doesn’t wash out my face cuz I’m so pale
