So I have 3 dresses in mind that I'm having some trouble picking from. Here's the thing; the mermaid dress wasn't my size, so I couldn't *actually* try it on. However, I totally love it. Do I go with...

I need to choose between these three dresses! My mom's (with the sleeves) we would take the sleeves off and replace with a small strap. They're all so different, I don't know what to do!
