Weddingbee boards

Hi everyone. Well I found a dress that I really like, but the stores I've visited or will visit only have it in an 8, which is a bit too small. I am an hourglass figure. Can this still give you a good idea of how the right size will look on you? I am a bit hestitant to get something that I haven't seen zipped up all the way! But I really like it and am running out of time to find something. We got engaged 2 weeks ago but the wedding is at the end of july!

My other favorite is:

This one I did try on in my size and liked it a lot. But I like the style of the first better maybe for our wedding by a lake. Thanks!
