S1·E3 Skin and Bones

When Jess hears that Dakota Dancer is going to paint Enid for a national exhibition, she cons her way into posing for him by convincing Enid that he wants to paint her nude. Although she wears a bikini during the posing, the unveiling reveals a portrait of her actually in the raw. She's mocked by the school until Liz and the gang set out to stop the painting from being exhibited. Meanwhile the students are upset when the principal pulls down an offending photo of himself off the graffiti wall; Liz learns to speak up for her rights.
