Common challenges include the visibility of the 'boob window,' potential wardrobe malfunctions with tight costumes, and the heat. Overcoming these involves meticulous construction of the costume, using strong adhesives or fasteners, choosing breathable fabrics, and carrying a repair kit with safety pins, fabric glue, and double-sided tape.
