Would you buy or hire a costume for an 80s night work do?

We've got an 80s costume work do coming up in a few weeks.

I don't really want to spend a lot of money on something I'll never wear again.

Most people I know are dressing up for it.

I was thinking of going to a costume shop to hire an 80s type of dress.

Would you hire instead of buying?
