Is this to short for a wedding dress?

So! I'm getting married may 20th! It's going to be a outside spring themed wedding. So I didn't want to go with a big heavy dress. I wanted something light and ariy. Simple. I found this one I really like! My fiancé said he liked it he just didn't know if some of my family would approve, ( some of them coming are pennacostal) I really love it though! I know it's my wedding and I can do as I please. But I don't want to upset my family on my special day either. I'm not sure how tall the model is in the pic below  ut I'm 5'7, do you think this dress is to short for a wedding dress? TTC for number one so if they happens before May might not be able to get the dress at all!! Haha :) thanks! 
This is me, I don't think it would look to short on me? I know you can't tell from a pic but you can kinda get in idea
