Pro tips

• Measure a t‑shirt you already own that fits well. Lay it flat, measure chest from armpit to armpit, double that number.
• If you’re between sizes, go up for a more relaxed feel or down for a neater look.
• Remember that ‘unisex’ means the cut is based on men’s sizing. Women often size down one or two sizes for a more tailored fit.

Where to Buy Official Merch

To get authentic NewJeans merchandise, always shop the official NewJeans store. That’s where you’ll find the Classic T‑Shirt, plus exclusive drops and limited editions. Third‑party sellers can’t guarantee quality or accuracy. For the full lineup, explore the full collection - from hoodies to polo shirts to tank tops.

Every official tee comes with size details and care instructions. Follow the wash care (cold water, tumble dry low) to keep your merch looking fresh.

FAQ

What is the fit of the NewJeans Classic T-Shirt? It’s a relaxed unisex fit. The 100% ring‑spun cotton is pre‑shrunk, so your size stays consistent after washing. You can size up for an oversized look or down for a closer fit.

How do I measure my chest for the right size? Use a soft tape measure around the fullest part of your chest, under your arms. Keep it level and snug. Compare your measurement to the size chart above.

Is the NewJeans t‑shirt true to size? Yes, the unisex sizing runs true to standard US sizing. Many fans find it matches their usual tee size. If you prefer a looser style, go one size up.

Can I return or exchange if the size is wrong? Yes, the official store offers hassle‑free returns and exchanges for unworn merch within 30 days. Check the store’s policy for details.
