You know that specific look. A character reaches up—maybe they’re stretching after a long study session, or maybe they’re just adjusting a ponytail—and suddenly the physics of their outfit go completely haywire. Getting collar shirt arms raised anime art to look "right" is a nightmare for most artists. It's one of those things that looks simple until you actually pick up a stylus.
Standard button-downs don't behave like spandex. They’re rigid. When the humerus rotates upward, the entire torso of the shirt wants to follow it, creating that iconic "tent" effect under the armpits. If you've ever scrolled through Pixiv or ArtStation and wondered why some professional pieces look effortless while others feel "stiff," it usually comes down to how the artist handles the tension points around the collar and the armholes.
The geometry of the armpit (and why it breaks your brain)
Most beginners think the sleeve is just a tube. It's not. In the world of collar shirt arms raised anime art, the sleeve is more like a hinge. When the arm goes up, the seam at the bottom of the armhole (the axial line) gets pulled taut. This isn't just a minor detail. It’s the foundation of the entire silhouette.
If you draw the shirt staying flat against the ribs while the arm is at a 180-degree angle, it looks like the character is wearing body paint. Real fabric bunches. It folds. You get these "Z-folds" or "pipe folds" that radiate from the armpit toward the chest and the shoulder blade. Honestly, the most common mistake is forgetting that the collar itself is anchored to the neck. As the arm lifts, the shoulder of the shirt rises, often obscuring the neck and pushing against the collar's base. This creates a triangular gap of shadow that defines the depth of the piece.
Think about the "Y-shape." In many classic 90s anime styles—think Neon Genesis Evangelion or Cowboy Bebop—the artists used very specific, sharp line work to denote where the fabric tension was highest. They didn’t just draw lines; they drew the force of the movement.
Why the collar matters more than the arm
The collar is the "anchor." Even when the arms are raised, the collar usually stays relatively fixed compared to the rest of the garment, because it's buttoned tight around the neck. This creates a fascinating visual contrast. You have the chaotic, messy folds of the lifted sleeve clashing against the rigid, structured circle of the collar.

If the character is wearing a tie, things get even weirder. The tie usually stays vertical due to gravity, while the shirt pulls upward behind it. This layering is what creates that "pro" look. You’ve probably noticed that in high-tier collar shirt arms raised anime art, the artist will often leave a bit of "ease" or extra fabric hanging over the belt line. If the shirt is tucked in, raising the arms pulls the hem out of the trousers. This is a tiny detail, but it adds a massive amount of realism to a fictional medium.
Anatomy vs. Fabric: The Great Struggle
You can't draw clothes if you don't know what's underneath. Period. When the arm is raised, the scapula rotates. The latissimus dorsi stretches. In anime, we often stylize these muscles, but the shirt still has to react to them.
- The Scapular Rotation: As the arm goes up, the shoulder blade moves outward. The shirt across the back becomes incredibly tight. If you don't show the fabric straining across the shoulder blades, the pose feels weak.
- The Deltoid Bump: The shoulder muscle (the deltoid) bunches up at the top. This creates a "step" in the line of the shirt. It’s not a smooth curve from the neck to the elbow. There’s a bump, then a dip, then the sleeve.
- The Armpit Gap: In a loose-fitting school uniform—a staple of the genre—there is often a "pocket" of air under the arm. Professional animators at studios like MAPPA or Kyoto Animation are masters of showing this "hollow" space.
Real-world references and the "Mirror Trick"
Kinda funny how many people try to wing it. If you want to master collar shirt arms raised anime art, you need to stand in front of a mirror with a literal H&M button-down and lift your arms. Look at where the buttons pull. Notice how the fabric between the second and third button might gap, revealing a hint of the undershirt or skin. That’s the kind of detail that makes a drawing go viral on Twitter.
Take a look at the works of artists like Shinkai Makoto. In films like Your Name, the clothing isn't just a texture; it’s a character. When Mitsuha or Taki reach up, the light hits the peaks of the folds and leaves the valleys in deep shadow. This "Chiaroscuro" effect on fabric is what gives anime its cinematic weight.
The "Tucked vs. Untucked" Dilemma
The physics change completely based on the hem. An untucked shirt will flow outward, almost like a bell. A tucked shirt creates "tension lines" that point directly toward the waistline. Most people forget that the shirt doesn't just pull up; it pulls in toward the center of the body.

If you're drawing a scene with high emotional stakes—maybe a character is frustrated or exhausted—showing the shirt "messily" pulled out of the waistband tells a story without words. It says they've been active. It says they're tired. It adds a layer of "lived-in" reality to the art.
Common misconceptions about anime fabric physics
"More folds equals more detail." Nope. That's a trap.
If you over-complicate the folds in collar shirt arms raised anime art, the character starts to look like they’re made of crumpled paper. The goal is "selective realism." You want to pick the three or four most important tension lines and ignore the rest. Usually, these are:
- The line from the armpit to the nipple.
- The line from the shoulder to the collarbone.
- The big fold at the elbow.
Everything else is just noise. If you look at the character designs in Jujutsu Kaisen, the line work is actually very clean. They use shadows to imply folds rather than drawing every single crease with a black line. This keeps the animation fluid while still looking "detailed."
Lighting the "Arms Raised" Pose
Shadows are your best friend here. When the arms are up, the torso is usually cast in shadow by the arms themselves. This creates a "frame" for the character's face.

- Cast Shadows: The arm will throw a long, dark shadow down the side of the ribs.
- Form Shadows: The underside of the sleeve will be dark, helping it "pop" against the lighter torso.
- Highlights: The very top edge of the shoulder—where the fabric is stretched thinnest—will catch the most light.
Using a "rim light" (a thin line of bright light along the edge of the silhouette) can help separate the arm from the background, which is crucial when the pose is complex. It prevents the character from looking like a blob of one color.
Actionable steps for your next piece
Don't just read about it. If you're trying to improve your collar shirt arms raised anime art, you need a systematic approach to the "anatomy of clothing."
Basically, start with the body first. Draw the character's torso and arms in the raised position completely naked (or in a simple mannequin style). Once the anatomy is solid, "wrap" the shirt around it. Start with the collar and the buttons—the "center line." Then, draw the "tension points" from the armpits.
Watch how the fabric "hangs" off the elbows. Gravity always wins. Even if the arms are up, the excess fabric of the sleeve will droop toward the ground. This contrast between the "pull" of the arm and the "hang" of gravity is the secret sauce.
Next, look at your line weight. Use thicker lines for the heavy folds under the arm and thinner lines for the light creases across the chest. This gives the drawing a sense of "gravity" and "mass."
Finally, check the "silhouette." If you filled the entire character in with black, would you still be able to tell their arms are raised? If the answer is no, your shirt is too bulky and is obscuring the pose. Trim the fabric back until the "action" of the pose is clear.
Focus on the "V-shape" created by the torso as it tapers toward the waist. The shirt should emphasize this, not hide it. By mastering these specific tension points and the interplay between the rigid collar and fluid sleeves, you'll move past the "stiff" look and into something that feels genuinely alive.
