I like the sleeveless one in number two, but the waist section could be a little smaller to accentuate her hips and show off her curves.

I like it!
The thing is, something doesn't have to be skintight/super short to make someone look attractive. These aren't nightclubbing dresses, they're casual day dresses. I enjoy looking good, but no way will I wear sky-high heels and latex dresses 24/7 to do it. Sometimes I'm bloated, and the cinched waists make me look like a packaged ham.
I'll admit that I'm not crazy about the maroon dress (maybe it's the whole outfit?), but I'd get the last one.
So overall, no, I don't think that this dress is supposed to be full-on sexy. The choker cutout adds a little touch of sexiness--it draws attention to the collarbones and chest--but really, it's just a casual and comfortable thing to wear, for when you don't "feel like it", but you want to look decent.
