Pastels This season, the message from designers on colour is this: any colour, so long as it's pastel. From spearmint to palest pink, to primrose, to duck egg blue and lovely lilacs - you decide. Spring's sugary palette courtesy of Lanvin, Givenchy, Louis Vuitton and Christopher Kane is a delicious sweetener to the season. With so much choice on offer, if you can't decide on a favourite hue, make like Prada and Phillip Lim and marry all shades together in the prettiest of confections. Too girlishly saccharine? Seek out the more womanly silhouettes (Alber Elbaz's sensuously draped dresses in pastel coloured luxe washed silk for Lanvin are strictly for grown ups only) and add edge with a flash of graphic black. Broderie anglaise Broderie anglaise is this season's surprise hit on the runways. But this traditional craftwork has come a long way since its Nineteenth Century roots. Now, think big. At Louis Vuitton, Marc Jacobs blew it up into jumbo proportions. This is a detail best played out in white or candy pastels and in flirty, ultra-feminine shapes, so look to sweet blouses, full circle skirts, and prairie dresses. If all over cut-out seems a step too far, look for separates with detail accents - a sprinkling of broderie anglaise trimming a neckline, or circling the hem of a skirt is oh so pretty. And the good news? It will keep you cool during a heat wave; think of it as built-in air conditioning... just breezy. White tailoring Starched white cotton might not be the easiest to wear, or, at first thought, particularly excite - where's the fancy? - but what is minimalist in colour is now maximalist in shape. Head-to-toe white tailoring is recast this summer, and the new idea? Sculptural shapes. Proportions are big and silhouettes are architectural - think wide, crease-front trousers paired with boxy, square-sleeved tops. Handle extra volume with care, those trousers need to be lifted on high heels and take your style cue from Phoebe Philo at Celine and rein in voluminous tops with a hip-cinching belt. N.B. Make friends with your dry cleaner (this is a whiter-than-white look; grubby shades just won't do) and keep it simple, it requires few add-ons. Tropicana Nothing says summer quite like exotic scenes comprising lush palm fronds and brightly coloured sun-drenched flowers. In fact, you can almost feel the humidity bouncing off those tropical prints by Stella McCartney, Joseph Altuzarra, and Massimiliano Giornetti at Salvatore Ferragamo this season. A sartorial livener, this is an all-over print best approached in an all-over way. Go it head-to-toe in the shape of cute knot-front shirts paired with cuffed shorts, one-shouldered gowns, and maxi dresses (if print isn't your thing, nod to the spirit and colour block in vivid hues of orange, turquoise, sunny yellow, fuchsia and emerald) and should proceedings verge on the kitsch, all the better. The idea is to actually look like you belong in Hawaii. But wherever you're headed for summer, this is a print that will transport you into holiday mode in an instant (tip: if you're set to enjoy a stay-cation, stock up on fake tan, these colours demand a sun-kissed glow).
