Wrap yourself in comfort with this unisex premium tee, featuring a subtle error-inspired aesthetic. Made from 100% combed cotton, it offers a soft, refined feel for everyday wear. The regular fit and classic crew neck create a timeless silhouette, while the pre-shrunk fabric helps maintain its shape wash after wash.

The design ERROR 400: near "integer" is inspired by real SQL-style error messages like "syntax error near...", which point to where something went wrong in a query. In real systems, these messages are longer and more specific, but this version strips it down to the essentials—keeping the structure recognizable while making it bold, minimal, and wearable.

Available in two refined dark tones: Black (images 1–4) and Coal (images 5–8). Choose Black for a sharper, high-contrast look. Choose Coal for a softer, muted variation with a more understated presence.

Minimal yet expressive, this T-shirt can be styled effortlessly for both casual and elevated looks.

Care Instructions: To maintain the quality, fit, and finish of this T-shirt, machine wash cold with similar colors. Turn inside out before washing and use a gentle cycle with mild detergent. Do not bleach or use fabric softeners. Do not tumble dry—air dry in shade to preserve shape and fabric integrity. If needed, use a cool iron inside out and avoid direct contact with prints.

Size Guide

Width in the table above refers to the Garment Width (measured flat, pit-to-pit).

For a more accurate fit, use Body Chest Fit as your primary reference when selecting your size. The formula is (Garment Width × 2) − Ease, with an 8 cm ease applied.

S: 86–94 cm
M: 96–104 cm
L: 105–113 cm
XL: 114–122 cm
2XL: 120–128 cm
3XL: 128–136 cm

Fit note: Designed for a standard fit that sits close to the body.

If you’re between sizes, choose based on your preferred fit. For example, a 104 cm chest sits at the upper end of M (96–104 cm) and just below L (105–113 cm)—choose M for a regular fit, or size up to L for a more relaxed, looser fit.

In the product images, the male model is wearing size M and the female model is wearing size S.
