Fantasy Advent Calendar: December 6 What's behind door six in our fantasy countdown to Christmas? Door number six is a portal to discreet yet luxurious style... Photo: Full Stop Studios. Delvaux is Belgium's best-kept secret. The oldest luxury goods brand in the world (founded in 1829), it occupies a status in its homeland comparable with Hermès in France or Loewe in Spain. A Delvaux conker-brown briefcase is a common coming-of-age present in Belgium, and the number of girls (some 500 per month) bringing their grandmothers' shoulder bags to the Delvaux factory in Brussels to have their love-worn straps replaced hints at the extent of inheritance. Often the style of the bags is so ancient that even the company's team of 35 craftsmen, some of whom have worked for Delvaux for more than 30 years, are unfamiliar with the design. Check out our fashionable Christmas gift guide Characterised by discreet designs with minimal branding - the only visible sign of a logo is a tiny gold D on the strap - Delvaux bags are built to last. The boxy Brillant is a case in point. Stitched together from 64 components, the design has hardly changed since its conception in 1958. The brand's made-to-order service allows clients to customise three sizes of Brillant, or the more contemporary Tempête design, using lizard, alligator or box calf, in a choice of classic colours. Hardware can also be specified - gold, silver or gunmetal - and initials embossed prior to stitching to minimise the creasing of the leather. Delivery time is a maximum of five months, but who wouldn't enjoy a belated Christmas gift in May? From £2,700, exclusively at Selfridges (0800-123400; selfridges.com).
