The term "birthday suit" refers to the state of being completely naked, as it humorously suggests that a person is in the same condition as they were when they were born. It highlights the natural, unadorned state of the human body, free from clothing. The phrase is often used in a lighthearted or playful context.
A birthday suit is what you were wearing when you were born - you are naked.
Because birthday suit means what you were like when you were born (naked) it does not actually mean an item of clothing.
