Showing shirt button when wearing a tux?

[lierre]

I have a shirt similar to the one below, and my bottom button shows just like on the model. Is this okay, or am I supposed to move the cummerbund higher? (I think it would look silly with my cummerbund any higher.) Thanks in advance!

I guess I'd spring for an extra stud.

I think his trousers are too low rise to be worn with that shirt, the bottom of the cummerbund is just at the waistband.

I would wear higher waisted trousers, find a vest that covered the button, or a different shirt, his shirt also looks not tucked in all the way.

I humbly suggest you check out the state of black tie thread, it is an awesome resource with a ton of genuinely helpful people who love wearing black tie.
