All of Alex Fierro's Canon Outfits
"Battered rose high-tops, skinny lime green corduroy pants, a pink-and-green argyle sweater-vest over a white tee, and another pink cashmere sweater wrapped around the waist like a kilt. The outfit reminded me of a jester’s motley, or the coloration of a venomous animal warning the whole world: Try me and you die."
"His wardrobe wasn’t gender specific. He wore his usual rose high-tops with skinny green jeans and a pink long-sleeved T-shirt. His hair, if anything, seemed a little longer, still green with black roots, now combed to one side in the shape of a wave."
"She was wearing pink-and-green flannel today over regular blue jeans. Her hiking boots were boringly practical, except the laces glittered pink metallic."
"Utgard-Loki had insisted we trade our regular footwear for bowling shoes—all of which were too big and Day-Glo orange and pink[...] Alex [...] seemed to like them."
"Alex’s white silk gown glowed with gold embroidery, from the tassels on her sleeves to the serpentine curls along the hem that swept her feet. A necklace of golden arcs curved at the base of her neck like an inverted rainbow. Pinned to her black-and-green ringlets was a white veil, pushed back to show her face: her two-toned eyes lined with delicate mascara, her lips colored a warm shade of red."
"He was wearing pink and green today, as usual, though I'd never seen this particular outfit before: lace-up leather boots, ultra-skinny rose jeans, an untucked lime dress shirt, and a checkered skinny tie as loose as a necklace. With his thick black Ray-Bans and his choppy green hair, he looked like he'd stepped off a New Wave album cover circa 1979."
"She wore green skinny jeans with a pink tank top, the front stitched in with an inappropriate hand gesture in glittery sequins. Her hair had started to grow out, the black roots making her look even more imposing, like a lion with a healthy mane."
“[A] mauve skirt hung to her knees over black leggings. Her green sleeveless top had given her no protection from the pavement… Her hair was longer than I’d ever seen it, a green ponytail sprouting from her black roots like a flame from Aegir’s hearth fire” (Thanks to @bakedbananners for this update.
"Alex Fierro stood over me— today's Alex, wearing a raincoat of such bright yellow I wondered if our ship [the Big Banana] had begun to assimilate her."
"She’d tied her yellow raincoat around her waist, revealing the plaid pink-and-green sweater-vest I thought of as her combat uniform."
"The first person to emerge from belowdecks was Alex Fierro, dressed like a 1950s greaser—her green-black hair slicked back, her white T-shirt tucked into lime-colored jeans." NOTE: she also takes back from Magnus a pair of pink-framed "Buddy Holly" sunglasses she had lent him for his trip to Alfheim.
"My friends were all dressed like me, in white wool [tunics and breeches], so we looked like a secret society of very clean monks—the Fellowship of the Bleach."
"As for Alex, she sat by an open window putting on a pair of hot-pink ski boots. Had she brought them with her? Had she tipped a servant a few kroner to find her a pair in Skadi’s supply closet? I had no idea, but she wouldn’t be skiing off to her death in bland white and gray. She wore a green fur cloak—Skadi must have skinned a few Grinches to make it—over her mauve jeans and green-and-pink sweater vest. To top off the look, she wore an Amelia Earhart–style aviator’s cap with her pink sunglasses."
A checkered "a cuadros" chainmail sweater-vest, which she herself made with Blitz's instruction (pg. 385-386).
A day later: "Alex leaned against the door frame, his arms crossed over his chain mail sweater vest, his pink glasses low on his nose." (pg. 404).
