Which dress style?

I went to my first appointment at David’s Bridal yesterday and surprisingly found that dresses I thought I wanted were not flattering on me. I wanted sleeve, lace, mermaid, and said no to strapless and spaghetti straps. Well turns out I hate sleeves, strapless and spaghetti looks best on me, but I still love lace!

I ended up really liking how the left photo felt on me and it would’ve been perfect but everyone including me felt the bottom of the dress was too bare. My mom didn’t like it. The right dress my mom picked out and surprisingly was flattering on me.

So I haven’t said yes yet, but at least I know what what flatters me. I keep searching online for the left side dress to something similar (see model photo). I do like my moms pick but I can’t help but going back to the style to the left dress. They both have longer trains but you can’t see in the right photo.
