My SO has an annual work dinner tmrw and I'm going as +1. He is most likely going with a grey tux. Please help me pick my dress!

all black mermaid style dress:
Con: it's tight and I a belly. By the time I finish eating I'm going to look 6 months pregnant! Probably better looking than the rest but the least comfy.


Loose Green dress:


Leopard print dress:
Con: I don't think this is 'formal enough. Uncertain about wearing this.

All black satin dress with long sleeves:
This one is made of a black satin like material. It is loose and flowy and the back is longer than the front.
I'm leaning more towards this one so i don't have to worry about holding my stomach in  

Help!

Black mermaid definitely

The first one is the only one that looks dressy enough to me. Maybe get some Spanx?

I like the last one best it looks the classiest.

Quoting Crystal Marie S.:" The first one is the only one that looks dressy enough to me. Maybe get some Spanx?"

Maybe I'll just start to deprive myself of food before tmrw evening  

You look beautiful in all of them but the last one is most flattering. If you choose the mermaid dress I would invest in some spanx

I like the first and last one

You're sweet, thank you  

I really like the first one, but if you don't feel as comfortable in that one I'd say the last one.

mermaid style dress.

the 1st one looks really nice on you!!! You can never go wrong with a little black dress

The only issue I have is they're all too casual, except #1

I think you'd look weird going to an evening event with SO wearing a tux, wearing an everyday dress.

It's satin, we would look something like this

I think number one, the last one would be okay if it didn't have the drawstring, that what to me makes it look too casual.
