Batman and formal wear questions

[Marcus]

- Batman Begins, the scene at his birthday party, OMG!: which jacket is Liam Neeson wearing!? That things looks fabulous!

- How do you tie a bowtie that does not have adjustable lengths, but is merely one single piece? Are those specified to the size of your neck?

- What is the english name for those elastic bands, that people used to put around their arm, to keep the shirt sleeve/cuff higher up on the wrist when writing?

Thanks.
