Lexi was always thin but has recently gained weight. Now she's too fat to fit into any of her clothes, except her bikinis. Now she can only wear bikinis. Her weight gain is mysterious and she can't lose an ounce. Accepting she'll be fat from now on, she's thrown away all her clothes, keeping only her bikinis to wear. She's not going to bother buying new clothes fearing she'll just outgrow them. Despite hating being fat, Lexi is fine wearing only bikinis.
