Thank you all for your advice! I ended up buying dres 1 and 2. I LOVE dress one and dress 2 just screams Vegas to me and it has an amazing back that I didn't show. If I don't wear dress one in Vegas I will use it has my rehersal dinner dress. I think it looks really classy. I might end up using it for both (don't tell on me!).
We are doing a long weekend in Vegas for my bachelorette party. We already booked our flights and I am extremely excited! I want to wear a white dress, but can not decide which one. Let me know what you think.
