NEW YORK, NY, UNITED STATES, July 28, 2026 /EINPresswire.com/ -- The luxury men’s underwear brand invites fans to celebrate confidence, comfort and exceptional Italian craftsmanship on August 5
Underwear is usually the first thing you put on in the morning, yet it rarely gets the attention it deserves. This National Underwear Day, Charlie by Matthew Zink is celebrating the confidence that starts with a great pair—and offering shoppers 30% Off to mark the occasion.
Observed each year on August 5, National Underwear Day began in 2003, created by online retailer Freshpair to celebrate underwear as an everyday essential, as well as the comfort and confidence it can bring. Since then, it has grown into a moment to embrace personal style, body confidence, and give this often-overlooked wardrobe staple the recognition it deserves.
For Charlie, underwear has always been a central focus—celebrated for the way it brings comfort, quality, confidence, and personal style together.
Luxury Fabrics Designed for Everyday Confidence
Charlie underwear is printed and crafted in Italy using premium fabrics chosen for their softness, breathability, stretch, and shape retention. The collection features refined essentials and standout statement styles, crafted from materials such as:
Italian cotton with elastane, delivering natural breathability, an ultra-soft feel and flexible two-way stretch.
Italian ribbed cotton, providing comfortable structure, softness and a close, flattering fit.
Lightweight Italian MicroModal, known for its smooth texture, luxurious softness and breathable comfort.
MicroModal-elastane blends, offering lightweight support, flexibility and a fit that moves naturally with the body.
From classic briefs and trunks to bikinis, thongs, and prints, every Charlie design combines comfort, confident style, and a sculpted fit that holds its shape over time. We make and print Charlie fabrics in Italy with carefully chosen materials to deliver exceptional quality and fit.
