As far as inventions go, dinky, yet oh-so-practical, belt bags are the sliced bread of the accessories world... Translation: Pretty damned difficult to beat.

This textured leather number from Wandler (available in baby blue, chocolate brown and taupe, as well as our squeaky clean ivory iteration) is a shining example – and not just because it’s glossed! Able to be worn in numerous ways, it’s the shape-shifting plus one that no outfit can do without.

One option is to cinch it at waist level, where it doubles up as a neat little number to accentuate an hourglass. For bonus points, you could emphasise this all the more with the ultimate contrast of a black puff-sleeve shirt à la Peter Do, exciting the eye southwards with We11done’s python-print trousers.

Alternatively, strap your Wandler in tight across the body and let it rest diagonally – and harness-like – atop your favourite trans-seasonal dress. We love it in partnership with something floaty and voluminous like Ganni’s glorious patchwork midi, which takes its design cues from the Wild, Wild West.

When loosened to hang down lower on the hip, the belt bag also proves that it can nail laid-back cool. Slip it on over Burberry's navy and red pleated kilt and Charles Jeffrey Loverboy's 'Ribcage' intarsia knit to serve as a focal point of this deliciously eclectic look.

And, with that, a hat-trick of sartorial wins is well and truly in the bag...
