The Cannes Film Festival is a huge moment for fashion, and rightly so — the event sees dozens of stars and starlets strut down the red carpet in their designer best, setting the tone for the year to come.

Of late Bollywood stars have been making a name for themselves on the Cannes red carpet. Aishwarya Rai has been a mainstay at Cannes going on 15 years now, and though Sonam Kapoor is a relatively new face to the event, she's made waves as a style star and fashionista of epic proportions.

So did Sonam and Aishwarya impress this time around? Yes and no.

What did Aishwarya get right? A beaded gown and old-Hollywood makeup

Finally, Aish moves away from clinging mermaid-style gowns and chooses a classic A-line Elie Saab silhouette. Win! The looks suits her. Her choice of colour for the gown is on point too: the nude is subtle, womanly, and doesn't leave much room for a fashion faux pas.

Flattering also is her rich maroon lip. She's on-trend as dark lips are all the rage right now.

What did Aishwarya get wrong? A purple lip. Cringe

Unfortunately, her choice of lipstick was not quite right the next time around. For her next appearance the actress wore a Rami Kadi floral embellished gown which we do NOT love. The off-shoulder sleeves are ill-fitting, cutting into her arms and creating all manner of bumps.

But that's a lesser offence.

What we really dislike is the lipstick, which is so... odd, that we can't help but wish we'd been around to run up to her and scrub it off. Honestly, a mauve lip reminds us of only one thing: a zombie movie. It doesn't work unless you're Lady Gaga. It most certainly doesn't work when you're a classic beauty like Aishwarya.

The lipstick is totally at odds with her princessy gown and is a major fashion fail for us. It even inspired a round of memes on the internet — unfortunate, but also hilarious.

Ouch.

What did Sonam Kapoor get right? This futuristic sari

This look wouldn't have been out of place if Sonam Kapoor had worn it to the Met Gala, with its fashion-meets-technology theme.

Sonam's Rimzim Dadu is visually stunning and endlessly fascinating. We wonder: what exactly is it made of? How does it manage to look like it's equal parts armour and delicate silk?

Luckily, Sonam made the right choice to keep the focus on her sari by opting for minimal hair and makeup. With this look, Sonam proves she's a style star for a reason.

What did Sonam get wrong? This overwhelming white gown

Sonam's looks work best when she plays up her young, sassy side, and this gown just doesn't do her personality justice.

The gown is by Ralph & Russo, a design house Sonam often favours. But this look is too severe for our liking.

We feel the fabric is too stiff and boxy for a summery affair like the Cannes Film Festival. And the cape? Overkill. Also, it's oddly reminiscent of Rihanna's iconic gold gown at last year's Met Gala.
