Alchemy Brothers

Our tees are crafted with a retail unisex fit, designed to provide a modern, streamlined look that fits closer to the body without being too tight. Made from lightweight, breathable 100% combed cotton, these shirts offer both comfort and style. Please note that they 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 more relaxed look. For women, we suggest selecting one size down for a more fitted look, or your regular unisex size for a comfortable, slightly looser fit.

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.
