The vibe was 1970s sexy-swag and the catwalk was packed with sharp, sexy separates modelled all at once with 10 denier tights and neck-scarves.
Slimane's model army (yes, Cara Delevingne included) strutted down the runway in plunging strap dresses, leather/denim mini skirts and silk shirts, tuxedo suits, fabulous feather outerwear and peep-toe heels.
If your outfit says anything next summer it needs to say CLASH.
Do funky florals, camouflage, leopard print, cherry print, sequins, stars and stripes - and do it across every fabric going. Leather, chiffon, silk and suede are your everything - invest in a boxy cropped leather jacket and a pair of hot pants and you're golden.
