Wedding dress

So I bought a wedding dress today.

Not getting married till about 2 years from now.

But I found this dress on a swap and shop page on Facebook and I fell in love with it.

It's gorgeous and I got it for $45.

It fits amazing on my top. The bottom I can't decide if it's too long or not. Obviously the back is long, because the train. But how does the front look? I'll be wearing probably shortish heels when we do actually get married. So my question is should I get this altered or no? Is it even something they could do?
