👕 Size & Fit

Our Natural Tees are available in Premium and Classic styles, both crafted with a retail unisex fit for a modern look that’s close to the body without being too tight. Made from breathable 100% cotton, they offer comfort and style in every wear. Classic uses high-quality natural cotton, so you may notice small specks in the fabric — a natural characteristic that adds authenticity and charm. All styles may shrink slightly after machine washing and drying.

For a standard fit, men should choose their usual size, or go up a size for a relaxed look. For women, we suggest selecting one size down for a fitted look, or your regular unisex size for a comfortable, slightly looser fit.

For precise measurements, check the size chart above 👆.

😎 Keep Your Koioki Tee Fresh

Flip It: Always flip your tee inside out before washing to keep that artwork poppin’.

Wash Cold, Stay Cool: Toss it in with cold water—keeps the fit and the vibe just right.

Gentle Vibes Only: Set your washer to gentle mode. Your tee (and the design) will thank you.

Chill on the Detergent: Use a mild detergent—no need to go heavy, let’s keep it smooth.

Bleach? Nah. Keep that harsh stuff away—no fading or ruining your look here.

Air Dry for the Win: Hang it up to dry for max freshness. If you’re in a hurry, low heat in the dryer works too.

No Hot Presses: If you need to iron, avoid the design. Flip the tee inside out or cover it up—let's keep the art clean.

🌿 Produced with eco-friendly practices

Every Koioki piece is made-to-order using the latest eco-friendly printing techniques, helping us reduce waste and avoid over-production.

Our apparel is crafted in factories that follow strict ethical standards.

Back in Black!

These anime shirts are straight fire 🔥 in black! The color contrast, the quality, and the comfort are just right! This is my second purchase of 4 shirts from this amazing company! I am now a long time customer! More Final Fantasy please!

Best gym shirts I've owned in awhile.

I'm currently deployed in the middle east and needed new shirts to go to the gym with. As you can imagine, weather here is rough. Heat rises to about 120 F every other day! My shirts are comfortable and I love the way they fit! It is my go-to shirt; even in this weather! After ordering, Koioki reached out to me via email to make sure I had my address correct and I received my shirts within a timely manner. I will be buying more shirts before the end of this deployment! Thank you for creating something that feels just as good as they look.

Better Than Anticipated

I had ordered 2 shirts and I was skeptical at first but upon receiving the shirts they were better than what was described/ showcased. The prints dont feel like sticker overlays they actually feel a part of the shirt. Im going to be getting more soon for sure.
