Acid wash oversized tees have a faded, marbled colour finish created by a chemical wash process applied to the fabric before printing. Regular oversized tees use solid, undyed fabric. Both use the same base cotton weight and print technique — the difference is entirely in the fabric treatment.
CREEPINS makes both. Here’s exactly what sets them apart, when to choose each, and why the wash process matters for the final look.
What is acid wash?
Acid wash (also called stone wash or bleach wash depending on the specific process) is a fabric treatment where the cotton is washed with chemicals — typically a chlorine bleach solution or pumice stones soaked in bleach — before the garment is cut and printed.
The chemical reacts unevenly with the fabric dye, creating a faded, irregular pattern where some areas lighten more than others. The result is a marbled, vintage-influenced look where no two pieces are exactly identical. Each acid wash tee comes out slightly different — same colourway, different pattern.
How acid wash is different from regular fabric
Regular oversized tees use solid-colour fabric — the cotton is dyed uniformly so the colour is consistent across the entire garment. The surface is even, the colour is flat, and the look is clean and straightforward.
Acid wash fabric has variation built in. The marbled effect means the tee has visual depth even before the graphic is added. When you put a screen or puff print on top of an acid wash base, the graphic interacts with the base texture — the result looks more layered and less like a standard printed tee.
Does acid wash affect fabric quality or durability?
When done correctly, acid wash does not significantly affect fabric strength. At CREEPINS, the wash process is applied to 240 GSM heavyweight cotton — the base fabric is substantial enough that the chemical treatment doesn’t compromise the weight or structure.
What acid wash does affect is colour behaviour over time. Acid wash tees will continue to fade slightly with washing — this is intentional and part of the aesthetic. The fading is gradual and adds to the vintage character rather than degrading the look. Washing in cold water slows this process significantly.
Which should you choose: acid wash or regular?
Choose acid wash if: You want a tee that looks vintage-influenced and textured. The graphic will sit against a varied base that adds visual complexity. Better for dark colourways (black acid wash, grey acid wash) where the marbling creates contrast without looking washed out.
Choose regular if: You want the graphic to be the centrepiece with a clean, flat background. Solid-colour bases work better for high-contrast prints and bold puff print graphics where you want the design to pop cleanly.
Both CREEPINS acid wash and regular oversized tees use the same 240 GSM cotton and the same screen and puff print process. The creative direction is the only difference.
How to care for acid wash tees
Cold water wash only. Acid wash fabric is more sensitive to hot water than regular fabric — hot washing accelerates fading beyond the gradual vintage effect and can cause uneven bleaching. Air dry; never tumble dry. Do not iron directly on the print.
The same rules apply to regular oversized tees, but they’re especially important for acid wash. For more on sizing, drops, and care, see our FAQ.
