Manny, you look gorgeous in the dress and I see no reason for concern, but it is as others said...you have to feel confident in it. And perhaps it's about where or when you choose to wear it?
I think with these body con dresses there is always that slight concern...is it the right venue, and so on. I have (and wear) a couple of body con sheaths. I actually love them. But for me they are my "date night" dresses. I did wear one to a work party once and felt fine in it, but these were really close colleagues and we were in "relax" mode.
Anyway, my point is, for me, the body con dress draws attention to my body in a way I don't really want except (mostly) on date night. So I wear those kinds of dresses with pleasure on those occasions and for my more casual day dresses tend to go for something like your linen dress (also cute). That's just what feels right to me.
I do however wear my body con tube skirts for super casual occasions. They are midis, which sort of mitigates the "sexy" vibe a little bit, but also, I tend to wear them with more voluminous tops, to "de-bombshell." Not that I am a bombshell by any means, LOL!!
So, for this dress, I would be wearing it on casual date nights with hubby or for at home dates. Or for nights with close friends when you go out or eat in but want to dress a bit festively.
