네온 수학 방정식여아 코튼 롱슬리브 티셔츠

Single jersey of 95% cotton and 5% elastane. It feels and breathes like a pure cotton tee — cotton is what touches your skin — while the touch of elastane lets it stretch, spring back and keep its shape wash after wash, so it doesn't bag out at the collar or sag at the hem the way 100% cotton can. We use reactive printing: the dye chemically bonds with the cotton fiber, so colors stay vivid through hundreds of washes — unlike sublimation, which only works on synthetics.

Every item is made on demand especially for you — production takes 2–7 days. Worldwide shipping is flat $10 — free on orders over $60; delivery takes 10–20 days to the US and Canada, and the exact arrival window for your country is shown on the product page and at checkout. You'll get a tracking number by email as soon as it ships.

Every product page has a size guide with body and garment measurements in centimeters and inches. Our labels follow European patterns and run one size larger than US labels from L up, so the guide shows the matching US size for each one — pick by that, not by the letter you usually wear. Adult sizes start at 3XS; the largest size depends on the style (2XL to 6XL). Kids sizes go by height and age.
