What size should I order if I normally wear a medium t-shirt?

Start with a medium in the hoodie, but check the chest measurement. If your chest is 40 inches, medium fits slim; large gives a relaxed fit. Also consider sleeve length and your preferred fit.

Will my Severance hoodie shrink after washing?

The 80/20 cotton-polyester blend can shrink 2-3% if you use hot water and high heat drying. To preserve the fit, wash cold and air dry.

How do I measure my chest for a hoodie?

Use a soft tape measure around the fullest part of your chest, under your armpits and across your shoulder blades. Keep it snug but not tight, and wear a thin t-shirt for accuracy.

Is the unisex sizing for Severance hoodies the same as men's?

Yes, unisex sizing is based on men's measurements. Women often need to size down for shoulders or size up for hips. Check the size chart and your own measurements.

What if I'm between sizes on the chart?

Go with the larger size for a relaxed fit or the smaller size for a fitted look. Consider your layering plans - if you'll wear a shirt underneath, size up.

Severance Hoodie Sizing Guide - Find Your Perfect Fit

Get the perfect fit for your Lumon-inspired Severance hoodie with this sizing guide. Learn to measure yourself, read the size chart, and avoid common mistakes.

Why Sizing Matters for Your Severance Hoodie

Most people grab their usual hoodie size without thinking. For a Severance hoodie, that approach can leave you swimming in fabric or squeezing into a fit that feels wrong. The show's aesthetic leans into clean lines and a slightly retro workwear vibe - your hoodie should match that precision.

This guide covers the severance hoodie sizing guide basics so you can order once and get it right. Whether you're after the classic fitted look like Mark's Lumon-issued gear or a more relaxed, off-duty style, knowing your measurements removes the guesswork.

How to Measure Your Chest and Length

Step 1: Chest Measurement

Use a soft measuring tape. Wrap it around the fullest part of your chest - usually right under the armpits and across the shoulder blades. Keep the tape snug but not tight. Write down the number in inches. > Pro tip: Wear a thin t-shirt when measuring. A bulky sweater adds 2-3 inches and throws off your size.

Step 2: Body Length

Measure from the top of your shoulder (where the seam of a well-fitting shirt sits) down to where you want the hem to fall. For a hoodie that hits at the hip, that's usually 26-28 inches for most adults.

Step 3: Sleeve Length

With your arm slightly bent, measure from the center back of your neck across the shoulder to the wrist bone. A common mistake is measuring with a straight arm - that adds extra length you don't need.

Understanding the Size Chart for Lumon-Inspired Hoodies

Our Lumon-inspired hoodies use a standard unisex fit. Here's what the numbers mean:

Size	Chest (inches)	Length (inches)	Sleeve (inches)
S	34-36	26	32
M	38-40	27	33.5
L	42-44	28	35
XL	46-48	29	36.5
2XL	50-52	30	38

These are taken from the actual garment laid flat, doubled for chest. If your chest measures 40 inches, a medium gives a slim fit and a large gives a relaxed fit.

What About Length Preference?

The length column matters more if you're tall or short. A 5'8" person wearing size M gets a hip-length look. At 6'2", the same size M will ride up your waist. Check the length measurement against your own torso length.

Fabric Shrinkage Note

The cotton-polyester blend (80/20) shrinks about 2-3% in the first wash if you use hot water. If you plan to machine dry on high, order one size up. Cold wash and air dry keeps the fit true to chart.

Tips for Choosing Between Fitted and Oversized Styles

For the Classic Lumon Look

Stick with your true size. The "Severance Macrodata Refinement Hoodie" in the fitted cut mirrors the show's sharp aesthetic - not baggy, not tight. It looks best when the shoulder seam lines up with your shoulder bone and the hem hits right at your hip.

For a Relaxed, Off-Duty Vibe

Size up once. This works especially well with the heavier 12 oz fleece versions. A size L instead of M gives you room to layer a crewneck underneath without feeling restricted. The sleeves run a bit longer too - great for thumbholes.

Avoid Going Two Sizes Up

Unless you want an intentionally oversized streetwear look (which isn't the Severance vibe), two sizes up makes the hoodie drape oddly. The shoulder seam drops too far, and the kangaroo pocket sits below your waist.

Common Sizing Mistakes and How to Avoid Them

Going off shirt size: Hoodies have a different cut than t-shirts. Your shirt size might be M, but the hoodie version of that same size can feel tighter due to the fleece lining. Always measure and check the chart.

Ignoring sleeve length: Chest fits fine, but sleeves end at your forearms. Sleeve length is often overlooked. Measure from your center back to your wrist - if it's 34 inches, don't order size S (32-inch sleeve).

Assuming unisex means men's: Unisex sizing is based on men's measurements. Women often need to size down for shoulder width or size up for hip room. If you have a defined waist, consider the tailored fit options some hoodies now offer.

Not accounting for layering: If you plan to wear a button-down under the hoodie, add 2 inches to your chest measurement before checking the chart. A size that fits with just a tee will feel restrictive with another layer.

Key Takeaways

Measure your chest, length, and sleeves before ordering - don't rely on your usual shirt size.
Match your size to the actual garment measurements, not generic sizing assumptions.
For a fitted Lumon-inspired look, stay true to size. For a relaxed fit, size up once.
Account for fabric shrinkage: if you hot wash/dry, order one size up.
Avoid common pitfalls like forgetting sleeve length or ignoring layering needs.
