But if you like your make-up to make a statement, rest assured: it's not all French insouciance on the Cannes red carpet. From Natalie Portman's daring electric blue lids to Lupita Nyong'o's vibrant fuchsia lips, Cannes is delivering plenty of inspiration for the colour-crazed too.
In terms of hair, tresses are sleek and shiny, with sweeping side parts, low chignons and screen siren curls as the glamour crowd grow out their lobs and begin to embrace longer lengths again. In a nod to '70s style, centre parts and braids are also making an appearance.

A vision in off-white Alexander McQueen at the Carol photocall, Rooney Mara kept her hair and make-up refreshingly simple. Her washed-and-dried tresses were scraped into a half bun with on-trend centre part, while her make-up look was modern beauty at its finest: groomed brows, faintly flushed cheeks and an earthy nude lip.
True to form, Portman is keeping it low key, with natural make-up and shiny, healthy hair. For her first Cannes 2015 red carpet appearance, she opted for a subtle taupe smokey eye and sleek waves to work back with her va-va-voom Dior red gown, while yesterday's pale blue and black silk bustier, also Dior, called for something a little more statement - DiorShow Khol in Pearly Turquoise No. 379 across the lids.
Israeli model and actress Bar Refaeli let her blue eyes do the talking, accessorised with a sheer base (DiorSkin Nude Tan BB cream and DiorSkin Nude Air Powder in Light Beige), lashings of mascara and rosy cheeks and lips - Dior Rouge Baume in Primerose No. 488.

Watts' peaches and cream complexion glowed thanks to radiant peachy pink blush - L'Oréal True Match in 160 Peach - and rosy lips. The timeless make-up look worked equally well with the voluminous modern up-do of her first red carpet appearance and the '20s waves she wore next.

Has Delevingne gone darker? The willowy blonde's newly caramel locks were loosely pulled into a braided chignon with centre part for a polished take on '70s style. Dramatic smokey eyes played up the dark hue of her deep-V gown.
Nyong'o rarely puts a foot wrong on the red carpet, and this year at Cannes was no exception. The only thing that could steal the spotlight from her emerald green Gucci gown? Her bold up-do, quickly christened a #fronut on Instagram and dripping with a diamond coronet - yet another example of the growing hair jewellery trend. We love her vibrant lipstick - Lancôme Hit List lined with Lancôme Le Crayon Lip Contour in Plum.
