You all have said it better but I would just like to concur that Layana was acting childish. I couldn't believe she was crying. While she might have told Daniel to edit or change something it was his design, his perfect tailoring that made his outfit what it was. It was especially impressive considering how little fabric Layana had 'generously' given him. She was a complete mess through the whole challenge and it was so odd to see her try to take credit for his work.
