Getting the right size for your Ironmouse merch means the difference between a hoodie that hangs perfectly and one that swallows you. After helping hundreds of Rat Army members find their fit, I've put together this guide with real measurements and community insight.

How to Measure Yourself for Ironmouse Merch

Get accurate measurements with a soft tape. Wear a thin shirt and stand naturally.

Chest: Measure around the fullest part of your chest, keeping the tape snug but not tight.
Waist: Measure around your natural waistline, about an inch above your belly button.
Hip: Stand with feet together and measure around the widest part of your hips.
Sleeve: Start from the center of your back (just below your neck), go over the shoulder, and down to your wrist bone.
Length: For tops, measure from the highest point of your shoulder down to where you want the hem to fall.

Write down these numbers in inches. Then compare them to the size charts on each product page. Pro tip: if you're between sizes, go up one for hoodies and tees if you prefer a relaxed look.

Understanding Ironmouse Hoodie Sizing

Classic Logo Hoodie

This is the most popular item in the store. The 10 oz fleece gives it a substantial feel but it also has a bit of give. Most fans find the Classic hoodie runs true to size with a relaxed, not baggy, fit. However, after washing, it may shrink slightly due to the cotton-poly blend. I recommend sizing up if you want an oversized look or plan to layer underneath.

Cropped Hoodie

Cropped hoodies are shorter in length, hitting around the waist. They have a more fitted silhouette through the body and sleeves. If you're tall or have a long torso, this might not be your best bet. For others, it creates a flattering proportion. Stick to your normal size because it's designed to be snug.

Premium Zip Hoodie

The zip hoodie offers more versatility for layering. It has a slimmer cut than the pullover, so consider going up one size if you want room to move. The side pockets are deep enough for a phone and wallet. Fans say the zip runs about a half size smaller than the classic pullover.

Ironmouse T-Shirt Fit Guide

T-shirts in the store come in two main styles: regular fit and fitted. The regular fit tees (like the Vox Akuma collab) are 100% combed ring-spun cotton with a soft hand. They hit at the hip and have a classic cut. I recommend your usual size unless you want a more tailored look, then size down.

Fitted tees (like the "Rat Army" graphic tee) use a tri-blend fabric that's stretchy and lightweight. They hug the body more. If you're between sizes, I'd go up one for a comfortable fit that isn't too tight.

Key tips for tees:

For a relaxed, casual vibe: order your normal size
For a slim, modern look: size down one
If you're tall (over 6'2"): the length may be short, so size up for extra length

Accessories Sizing Tips

Hats, beanies, and bags are often one-size-fits-most. The dad hat has an adjustable snapback strap that fits head circumferences from 22 to 24 inches. It's a low-profile shape, good for running or lounging. Beanies are stretchy ribbed knit that fits most adults, but if you have a larger head (24+ inches), it may feel snug.

Backpacks and tote bags don't have sizing, but check the dimensions listed on the product page. The canvas tote is 15" x 15" with 20" straps - plenty for everyday carry.

Final Tips for the Perfect Fit

1. Measure yourself, not your old shirt - shirts stretch over time, so going off worn measurements leads to wrong sizing. 2. Read product-specific size charts - each item may have different measurements depending on manufacturer. 3. Check the fabric content - 100% cotton shrinks more than blends. If you'll dry on high heat, size up. 4. Read recent reviews - fans often share if an item runs large or small. Check the latest comments. 5. When in doubt, go up - oversized looks are forgiving; too small is uncomfortable.

Getting your Ironmouse merch sizing right means you'll wear it more often. Follow these steps and you'll look and feel confident in your Rat Army gear. - -

FAQ

What size should I get if I'm between sizes in the size chart?

If your measurements fall between two sizes, I recommend going up to the larger size, especially for hoodies and tees. It gives you room to move and accounts for potential shrinkage.

Do Ironmouse hoodies run small or large?

The classic pullover hoodie runs true to size but can shrink slightly after washing. The zip hoodie runs about a half size small. Always check the specific product size chart as materials vary.

How should I wash my Ironmouse merch to avoid shrinkage?

Wash in cold water on a gentle cycle and tumble dry on low heat. For 100% cotton items, air drying is best to preserve the fit. Avoid high heat which causes significant shrinkage.

What's the best hoodie size for an oversized look?

For an oversized fit, go up 2 sizes from your normal. The classic hoodie has a relaxed cut, so 2 sizes up gives a fashionable slouchy look without being absurdly large.

Is the cropped hoodie true to size?

Yes, the cropped hoodie is designed to fit snugly. Order your usual size. If you're between sizes, size up for a slightly looser fit, but be aware the length will remain short.
