Wax London's shirting contingent features a bevy of prints and patterns to choose from, but this red and blue floral iteration of the brand's bestselling Didcot Shirt gets our pick. Its retro-inspired camp collar cut and lightweight, breezy feel makes it an instant summer classic.

ISTO. Chambray Shirt

Lisbon-based label ISTO.'s workwear-inspired Chambray Shirt is a casual classic. Crafted from 100% organic cotton, it's soft yet ultra-durable, so it's guaranteed to stand the test of time. Roll up the sleeves and leave the top two buttons undone for a relaxed everyday look that screams off-duty.

Closed Utility Long Sleeve Shirt

With its roots in denim production, German label Closed remains a fantastic go-to for relaxed everyday staples, casual shirts included. This utilitarian-inspired long-sleeve shirt is crafted in Italy from lightweight twill, and dyed naturally for a washed-out look. Embrace the workwear aesthetic by teaming it with loose cargo trousers and canvas high-top trainers.

ASKET The Denim Shirt

The denim shirt is a casual wardrobe hero that will inject just the right amount of laid-back elegance into any ensemble. This version from ASKET is crafted from heavyweight organic cotton and finished with mother of pearl buttons for an elevated take on the menswear staple. Wear it with chinos or jeans if you're feeling brave enough to tackle the double denim trend.

CDLP Pool Shirt

CDLP creates some of the most cutting-edge casual shirts for men, both in terms of style and construction.

Stylish and sustainable, what's not to love?

L'Estrange Collarless Linen All Day Shirt

Grandad collar shirts tend to be rather divisive, but here at OPUMO, we're firm fans – particularly of this style by L'Estrange. Crafted from a silky linen-cotton blend with just a hint of stretch, it's designed to be worn all year round. Team it with shorts and sandals in summer and jeans and Chelsea boots in the colder months.

Hamilton and Hare Pique Open Collar Shirt

Hamilton and Hare is best-known for its oh-so-comfy underwear, but it also happens to make a great line of casual shirts, as evidenced by this camp collar pique cotton style. With a relaxed fit and super-soft construction, it's perfect for poolside lounging and best teamed with an afternoon spritz.

Neutrale Balearic Linen Shirt

Spanish label Neutrale creates relaxed essentials inspired by the natural beauty of the Mediterranean. Its 100% linen Balearic Shirt channels this through a relaxed, softly draped silhouette and sunset-coloured buttons. Complete the holiday-ready look with a fresh tan and salty skin.
