Corsets have been featured in several different anime series. Here are some examples:
4 minutes in, Eleanor is encouraging her maid Annie to go very tight corset
10m55s in, Martha tries to force Emma into a corset.
aka "Black Butler" has a somewhat yaoi-eroticized corset-dressing scene:
The character Nico Robin wears a corset-like top mostly to hold her chest in.
In this series, one of the villains name is Corset and a corset is actually part of ihm.
