How Do I Change My Poshmark Username?

The ability to change your Poshmark username is not yet an option (as of March 2, 2019). There is a possibility of this changing in the future, however.

For now, Poshmark asks that you contact their support team if you would like to request a username change. I am however uncertain of the success rate in doing so.
