Summarize the following:
The only sure way to get a cape for your character is by attending a MineCon event, which only happens once per year. If you can't attend MineCon, you can try using a mod to get a cape for your character. The email address that you use to sign up for MineCon is the email address to which your cape's link will be sent, so make sure that you use the correct email. When you attend MineCon, your ticket will be scanned. This allows Mojang to track your attendance and send a link to your registered email address. MineCon 2018 will be held in an online stream, meaning that it's technically free to view. For this reason, MineCon 2018's presentation might have a different method for confirming your attendance. Sometime during or after MineCon, you should receive an email from Mojang with a link to your cape. Click the link in the email from Mojang, then sign into your Minecraft account to add the cape to your character's model on your computer. When you're wearing it, anyone with whom you're playing multiplayer will be able to see the cape. Besides MineCon capes, the only other players to receive capes have been a select few that have been heavily involved in the development and community aspects of Minecraft. Obtaining a cape in this way isn't really feasible due to the sheer number of people who help out with Minecraft's development and community. To do so: Go to https://minecraft.net/en-us/profile/ Log into your profile. Click the character model drop-down menu. Click the cape version of your preferred character model.
Find an upcoming official Minecraft event. Use your Minecraft email address to sign up for MineCon. Make sure that your MineCon ticket gets scanned. Check your email inbox for a cape redeem link. Redeem your cape. Get involved in Minecraft development. Enable your cape if you have one.
