Meet Our EveryWear Fabric
At Ameliora, we believe clothing should work as hard as you do. That’s why we created our EveryWear Fabric engineered for modern life and perfect for every wear, everywhere.
Lightweight, breathable, and crafted with four-way stretch and UPF 50+ sun protection, it adapts seamlessly to your every move. Whether you’re catching a flight, running between meetings, or navigating the rhythm of everyday life, our EveryWear fabric keeps you comfortable without sacrificing elegance.
Fit is everything
Every seam, curve, and cut is intentional. We choose craftsmanship over shortcuts to create garments that move with you, flatter your shape, and last for years.
Curved Seams
Thoughtfully placed curved seams follow the body’s natural lines, creating a polished, tailored look that feels effortless.
Back Neck Drop
A precisely curved back neckline ensures our shirts sit comfortably at the shoulders, flatter posture, and feel natural all day.
Generous Grade
We design with generous grading, adding more room where it matters so every size drapes with equal comfort and elegance.
Technical Designers
Our team trained with master Italian pattern makers and studied every detail construction so each piece is engineered to fit real bodies.
