Thylie was founded by Monika Hess – a seamstress, buyer, and entrepreneur with decades of experience in the premium fashion segment. Thylie was born out of the desire to offer a T-shirt that truly fits and brings lasting joy. Our label was born from extensive experience and a genuine understanding of the discerning woman's needs for a high-quality basic.

• Double front panels to prevent transparency
• figure-flattering fits
• Developed materials that feel extremely good – all day long.

We produce using the finest Peruvian Pima cotton yarn, one of the highest quality cottons in the world, also known as the silk of South America. It is exceptionally soft, retains its shape, regulates temperature, and is extremely pleasant against the skin – even after many washes.

Our fabrics and cuts are designed so that you can feel the difference directly, not just see it. Each shirt is crafted with precision to guarantee durability, comfort, and elegance.

From yarn to hangtag, we produce everything in Peru, in close collaboration with certified partners and their families.

Thylie is a Swiss family business and a young label that was built with a lot of passion and is constantly being developed further.

We are proud of what we have already achieved and especially grateful for the many positive responses and the personal exchange with our customers.

Timeless, stylish and uncompromising in quality.

We deliberately focused on the essentials:

• first-class materials

• meticulous craftsmanship

• sustainable production practices

We believe in slow fashion, in clothing that lasts, accompanies you and brings joy for a long time.
