Style Information
Inspired by the quiet beauty of Japanese design, The MIZU Linen Shirt is an expression of effortless simplicity. Crafted from 100% premium European linen, it combines clean lines, relaxed proportions and thoughtful detailing to create a shirt that feels as refined as it is comfortable.
At its heart is PIER ST BARTH’s Signature Open Collar, a softly structured, Japanese-inspired one-piece collar designed to sit naturally open at the neck. Paired with a clean open-front placket, it creates a relaxed silhouette that feels modern, understated and effortlessly elegant.
Twin chest patch pockets lend a subtle workwear influence, while the straight hem is designed to be worn untucked, giving the shirt its balanced, boxy profile. Garment-washed for exceptional softness, the breathable linen drapes beautifully and becomes even more comfortable with every wear.
Whether paired with relaxed linen trousers, tailored shorts or worn open over swimwear, The MIZU embodies timeless coastal style with an unmistakable sense of quiet luxury.

Care Instructions
When washing linen shirts, if you’re using a washing machine, ensure that you’re using a gentle or delicate wash (on cold or warm) with a low spin cycle. Add a subtle mix of detergent and wash your linen with like, light materials that won’t crowd in the machine - if there’s not enough room to move in the machine, the linen can get tangled and stretch within the load. Alternatively, you can hand-wash your linen with a soft detergent, just make sure you don’t soak it for a long period of time - just dunk it into a cold-water tub with baby-like soap and gently rinse.
TIP: Always review the care instructions for any individual linen item, as each piece could potentially have its own unique washing and drying needs.
