In Greek mythology, Athena clothed Pandora before she was sent to Epimetheus.
Hesiod’s Works and Days describes the gods contributing different qualities and adornments to Pandora. Athena, the goddess associated with wisdom, warfare, and crafts, gave her clothing or dressed her in garments. This detail is part of the divine construction of Pandora as a complete, attractive human figure.
Other gods also contribute to her presentation. Aphrodite gives beauty or grace, while Hermes gives speech and a deceptive nature in the Hesiodic account. These roles are distinct, so Athena should not be substituted for the goddess associated with beauty.
The story is sometimes illustrated with later artistic conventions that do not identify every gift precisely. The answer here follows the surviving Hesiodic account rather than a modern film, game, or painting.
