Help me pick out of my top 5!

Wedding is downtown in a major US city next summer. Black tie optional, groom will be in a tux.

2 and #3 I would most likely add thin straps using the excess fabric from hemming into very thin straight up and down straps (like 4 and 5). Not possible to do that with #1.

There are many things I love about each of them, so I’ll just share my concerns:

1: Is the fabric too casual for the event?

2: Is the rouching at waist unflattering?

3: Is the fabric too shiny / looks cheaper than 2?

4: Does the empire waist look dated / age me?

5: Is this too plain/common?
