Can you tag someone in an Instagram Story using a traveler's account?

Yes, you can tag someone in an Instagram Story using a fashion designer's account or any other Instagram account, as long as the account is public. To tag someone, you can use the "mention" feature while creating your story. When you type "@" followed by the account's username, Instagram will suggest usernames that match what you've typed. Once you select the desired account, it will be highlighted and underlined in your story. When your followers view your story, they can tap on the username to visit the fashion designer's profile.

However, it's important to note that you cannot tag someone in a post using another account; you can only do this with your own account.
