Jeremy Belpois Code Lyoko Costume Guide

#CommissionsEarned

What You’ll Need

Jeremy Belpois spends nearly the entirety of Code Lyoko stationed in the abandoned factory’s lab chair, orchestrating transfers and fighting off X.A.N.A.’s attacks from behind a keyboard. His design reflects a bookish, utilitarian boarding school student rather than an action hero, built around oversized turtlenecks, cropped hems, and round glasses.

Because Jeremy operates in the real world rather than inside the digital sectors, his outfit relies on casual wardrobe staples instead of armor or sci-fi bodysuits. The challenge comes down to silhouettes and color blocking, especially since the show’s stylized proportions give him an oversized collar and distinctly short trousers.

The Classic Seasons 1–3 Outfit

For the first three seasons, Jeremy wears a deep burgundy turtleneck sweater paired with olive green cropped pants. The sweater has a high neck that rolls snugly against the throat, with long sleeves that bunch slightly around the wrists. Choosing a Burgundy Turtleneck Sweater with a medium knit gives the top enough structure to hold that defined roll without collapsing flat against the chest.

His pants sit at a distinct capri length, ending well above the ankles and exposing several inches of bare lower leg. The Olive Green Cropped Pants match this proportion closely. If you start with standard straight-leg olive chinos, hem them or roll the cuffs upward toward mid-calf so they do not fall like regular trousers.

The Season 4 Wardrobe Update

When the series updated the cast’s real-world wardrobes in Season 4, Jeremy switched to a cooler palette. The deep red was swapped for a Light Blue Turtleneck Sweater, while the bottoms shifted to sand-colored Khaki Ankle Pants. The overall silhouette remained identical: a clean, folded neck paired with trousers cut short above the footwear.

If you are putting together a group with friends cosplaying the later seasons, this version lines up with the team’s updated designs. The lighter blue knit also shows up distinctly against darker convention backdrops.

Footwear Choices

Jeremy’s shoes are simple slip-on footwear in a saturated royal blue. In animation, they resemble backless indoor clogs or low-profile skater shoes with flat white outsoles.

A pair of Blue and White Slip On Sneakers provides the right contrast and stays secure on your feet through a full day of walking. Alternatively, Blue Mule Clogs match the open-heel, slide-in shape seen in several close-up shots of the lab chair, though they offer less heel support during long walks. Whichever route you choose, skip socks entirely, as Jeremy’s bare ankles are a consistent visual element of his character model.

Glasses and Hair

The round wire glasses are the most defining feature on Jeremy’s face. In the show, the frames have an oval shape with thin rims that sit straight across the bridge of his nose. The Oval Rimmed Glasses fit this profile neatly. If you wear prescription lenses, you can either swap clear non-prescription lenses into costume frames while wearing contacts, or source an inexpensive wireframe pair matching your actual prescription.

Jeremy’s hair is a warm, sandy blond cut into a short, messy style with long bangs parted slightly off-center and side pieces that brush down past the ears. A short Blond Wig works well as a base. You will want to use a light styling wax or hairspray to separate the bangs into soft, rounded clumps rather than leaving the fibers completely smooth. Keeping the volume modest around the crown prevents the wig from looking too top-heavy against the glasses.

Laptop and Prop Options

While Jeremy rarely carries physical weapons, an old silver laptop or a thick spiral-bound notebook filled with code printouts works naturally in photos. A compact headset with an adjustable boom mic also calls back to his communication setup when guiding the team through Lyoko.
