In Lincoln's fantasy about being at the grown up table, Luna, like everyone, dresses in fancy attire. Her outfit consisted of a sleeveless dinner gown, dangly white pearl earrings and purple high heel shoes.
In a flashback where Leni handed her bike down to Luna, who made it into a custom chopper, she wore shades, gloves and a bike helmet with a spike sticking out like a Pickelhaube, a former German military helmet.
When Lincoln and Clyde get thrown in the mall's jail, Luna disguises herself as her mother in order to bust them out. However, Bobby easily sees through the disguise and gets her locked up with them.
During Luna's story of how she got into rock and roll, she was a gentle and sweet girly girl. She originally had longer hair that went down to her shoulders, a girlish light purple shirt, white earrings, the same square-patterned skirt, white socks worn high and black Mary Jane shoes.
Luna dresses up as a computer nerd to help Mr. Grouse prepare for an IT job interview. She wears a pair of brown dress shoes, blue jeans, brown suspenders, a white dress shirt, a red necktie, a pair of purple semicircular glasses and paper clip earrings.
In Lily's imagination, Luna wears a shirt like her usual one but with a white circle with a pink triangle on it instead of a skull. She also wears a black belt instead of her usual one, wears only one bracelet and wears a safety pin instead of a paper clip for her earring.
Luna's outfit during Flip's comedy is shown to be a light purple shirt with a torn piece on the upper right side, a small part of a black bra being exposed, and a purple plaid jacket tied around her waist. She still retains her purple boots and paperclip earrings, but now wears a dark gray beanie.
In a small fantasy, Luna is seen with her normal clothes but with her left boot removed, revealing it to be light purple sock with dark patch on the toes when she wrote in her diary that she got a tattoo. The tattoo she has is shown to be a flaming skull.
Luna was trying on outfits in her room. She tried a summer outfit which consisted of red sunglasses, a pink T-shirt, a yellow short-sleeved jacket with pink flowers, orange frilly shorts, and black flip-flops.
Then, she tried a winter outfit which consisted of a red beanie, a slightly different earring, a seafoam green scarf, a green jacket, a dark green skirt, seafoam green leggings, white socks, and boots like her usual ones but green.
Then, she tried on pink tights with yellow boots that had springs on the soles.
Luna came to the concert in a purple dress that was damaged by Lori and Leni.
In "It's Just a Phase", Luna is seen as a one-year-old wearing bracelets like her usual ones, plus a shirt that looks like her regular one but with a smooth neckline and it's a T-shirt rather than a tank top.
She wears a purple sweater with patterns of bells on the front and sleeves, musical notes embroidered on the collar and hem, and a red button with a white arrow that plays Christmas carols and is marked "Carol Button" in red letters.
She wears a light purple headband with lilac stars, a matching mask, pants, and gloves, a shirt like her usual one but longer and without the skull, purple star-shaped earrings, dark purple flats, and fishnets on her ankles and arms.
