Big Slit T-shirt

Thanks to the deep side slits, this T-shirt offers a flowing, feminine silhouette with ease of movement. It’s a stress-free piece that completes a look on its own—our Big Slit T-shirt designed for everyday simplicity and comfort.

Under the wide blue skies, in the bright sunlight and ocean breeze of Australia, this cotton was slowly nurtured by nature. At 45R, we place great value on comfort—the fabric delivers a smooth, refined feel that reflects the quiet elegance of Japanese craftsmanship.

By spinning slightly thicker slub yarn and knitting it into jersey, we’ve created a fabric that feels light against the skin. With each wear, the texture deepens, making it a material that only grows more comfortable and expressive over time.
