When you register, Marni Online Store recognizes the country in which you are located and automatically associates it to your account, which will be active only for that country's version of the site. If My Account does not recognize your email address or password, verify that you are navigating the version of the site on which you registered the account.
If you forgot your password, click the "Forgot your password?" link on the Login page and follow the procedure to change it.
