As a member of a registered event, you should have received an email notifying you that you were added as a member to someone’s Event Manager account. Within that email, you should also have a special link that allows you to enter your sizes and checkout.
We recommend searching your email for a message with the following subject line: “Your Tuxedo Sizes are Needed”
If you did not receive this email or cannot find the link: You can try looking up your size-entry link using the Size Form Lookup Tool and entering your email address.
