Does this look too small?

Does this suit look too small to you? I'm not quite sure.

In looking for a tiny suit for Sam & Megan's wedding, our neighbor had one. Unfortunately, it's too tiny.

The shirt has button holes that are supposed to match up with buttons on the inside of the pants. Notice there's a very big gap between the two.

But maybe just the tie and vest will work, Chippendale style.

But part of me wants to sing "Fat guy in a little coat. Fat guy in a little coat!"
