This spring/summer, it's not the size or shape of your bag that counts, it's the colour. In addition to popular neutrals and acid brights, bags come in a rainbow of colours, most notably sea blues and fruity mandarins. Colour blocking in two or three tones is spring's most striking theme, as is pared-down boxy shapes. The spring palette at ck Calvin Klein for women uses bold, minimalist colour blocking to dramatic effect. Contrasting or complementary colours highlight the bags' main body and handles. The palette is not for the shy - chartreuse yellow, bright mandarin and vibrant pink are stand-outs, in addition to the brand's signature black and nude. Soft, tumbled leathers create clean silhouettes with strong lines available as satchels, totes, slings and clutches. The ck Calvin Klein's men's line captures timeless functionality and practical styling. Square lines and shapes have been softened and updated with tumbled leather in bright mandarin or classic tones of black, bone, navy and light grey. Mod two-tone colour blocking is also key for men. LeSportsac has introduced three fun and functional totes - the metallic Carryall, the classic black City and the whimsically colourful Picnic Tote - a blue gingham topped with pastries, teacups and card games. These join the Classic collection, which this season is all about pastels, polka dots and ruffles in a nod to the gardens of spring. For men, LeSportsac has a selection of bags in its signature rip-stop nylon that are practical for guys on the go, yet refined enough for the office. Road Block features a reflective stripe and is a nod towards denim fashion. Wired is a plaid pattern in blue with orange accents and toned down in black. Staying true to its original values, Coach has drawn on its extensive archives to celebrate its 70th anniversary. Classic designs and iconic hardware have been given a fresh twist with the infusion of colour-blocked Italian waxed calfskin, as well as limited editions and commemorative anniversary styles. First introduced 20 years ago, the Willis bag is one of Coach's most popular designs. The Poppy Willis features a faithful reproduction of the original's iconic dowel detail, trigger clip and signature oval turnlock, but is updated with softer corners and a modern colour palette. Coach looked to the exclusive beach towns favoured by well-heeled New Yorkers when designing the Hamptons collection. This year it returns with a special anniversary collection of totes in a range of materials including straw, terrycloth, washed suede and canvas. Coach revived decades-old logos for its men's collection. It also made use of artisanal techniques like hand-burnishing, and reincorporated the internal hanging pockets found in their unlined men's business bags produced through the 1960s and 1970s. In a first for Furla, the brand has entrusted its art direction to Italian artist and performer Sissi. Sissi has reinterpreted the brand's Candy bag, with each one featuring different materials, colours and details that express a specific style and state of mind. Colours are taken from nature - from the blue of the sky, to the black and white of rocks and pebbles, and warm earth tones of honey, red and yellow. Fabrics include bullhide, vintage-effect leather, coarse canvas, reptile skin and hi-tech materials such as neoprene. Sequoia has placed an emphasis on colour blocking, with contrasting exteriors and interiors, piping and edges. They have grouped their designs into a variety of themes, such as structured modernity in 1950s styles, loud tropical prints in the safari collection, and cool sea blues in 'by the sea'. A range of coated canvas bags incorporate exotic prints, with leather, cotton and metal elements.
