FAQS ABOUT OVERSIZED T-SHIRTS – ANSWERS TO YOUR QUESTIONS

Fit, material, or the meaning behind our designs – here you'll find the most important answers about our oversized T-shirts. Everything you need to know before choosing your new gear.

What is an oversized T-shirt?

An oversized T-shirt is a loose-fitting shirt with a wide silhouette, dropped shoulders, and more freedom of movement. It originated in the hip-hop and skater culture of the 90s and has established itself as a symbol of independence, freedom, and self-expression. Today, the oversized look is an integral part of modern streetwear and is also popular in our community.

Why is the oversized look so popular?

The trend comes from the street and gym scene, where clothing doesn't constrict but supports. An oversized shirt looks casual, offers full freedom of movement and at the same time emphasizes strength and self-confidence. Especially in combination with heavy fabrics and striking prints, the look stands for a calm, casual and confident presence.

What distinguishes oversized T-shirts from regular shirts?

Unlike regular-fit shirts, an oversized T-shirt is wider and longer. The fabric is not tight-fitting, but casual. This cut ensures a modern look without compromising on function – ideal for training, leisure, and everyday wear.

How does the Brothers in Arms oversized T-shirt fit?

Our oversized T-shirts for men have a generous but well-thought-out cut. If you are between two sizes, we recommend choosing one size smaller. Sizes range from S to 3XL, so every body type can find the right fit.

What material are the oversized shirts made of?

Each oversized shirt is made from heavyweight premium cotton. The fabric feels solid, remains breathable, and is comfortable to wear. The hand-picked colors and high-quality prints are produced in Germany for long-lasting quality you can see and feel.

How do I properly care for my oversized T-shirt?

Wash your shirt inside out at 30°C, avoid the dryer, and do not iron the print directly. This will keep the material stable and the print color-fast—even after many washes.
