Thai actress Becky Armstrong had a buzzworthy run at this year’s Festival de Cannes.
Every year, filmmakers, critics and celebrities jet to Cannes in Southern France to attend the city’s film festival. More than a platform for creatives to share their latest endeavors, Cannes is the finest celebration of the visual arts. Attendees treat red carpets and press events as personal fashion shows, bringing their A-game to every appearance.
After her debut at the 2024 Cannes Film Festival, Thai actress Rebecca Patricia Armstrong, best known as Becky, made a stunning return to this year’s event with a series of monochromatic looks.
Below, No Manner breaks down Becky’s best style moments at Cannes.
The Summer-Ready White Set
The summer heat usually means one clothing article is guaranteed to rise in popularity: white pants. Be it linen, denim or regular trousers, a pair of white pants is, undeniably, a summer essential. If you weren’t already convinced, Becky made a strong case for the all-white ensemble at Cannes. On the first day of the festival, Becky posed in a strapless white top and tailored white trousers. The actress wore minimalist gold jewelry and white sandals for a dress-down, yet well-coordinated, effect.
A Moment for Pink
On her first day at the festival, Becky posed in the lobby of the Hotel Martinez in an asymmetrical hot pink dress. The actress wore the VINNPATARARIN piece with white shorts and baby pink flats for a simple, feminine look. Bringing a bit of bling to the outfit — and a tasteful use of the sandwich styling method — was a pair of drop earrings that complemented the hardware on Becky’s Roger Vivier ballerinas.
During a separate outing, Becky wore a different pink dress by vela de (เวลาดี), subtly honoring her birthplace of Bangkok. The cowl neck one-piece was an elevated take on the pastel color and featured a slight cinch at the waist and draping details. For this look, Becky kept her glam simple, wearing minimal makeup and her hair tied back in subtle curls.
Business Done Casual
Fans of office-inspired high fashion rejoice! Becky delivered lessons on business casual as she posed for photos outside the Hotel Martinez. Her two-piece set embodied minimal chic. Paired with knee-high boots, the cropped blazer and tailored black shorts were an effortless take on a modernized summer suit. Wearing black sunglasses, gold earrings and a matching Chanel bag, Becky perfectly demonstrated why less can really be more.
The actress put a spin on the same outfit formula as she stepped out in Cannes for other L’Oréal commitments. Becky wore a cut-out cropped jacket, wide-legged patent leather pants and a pair of Roger Vivier ankle boots.
Case 137 Red Carpet
For her appearance at the red carpet for Case 137, Becky wore a nude gown by Lebanese designer Nicolas Jebran. A tale of masterful craftsmanship, the gown featured one gloved sleeve and a high slit on the left thigh. Becky opted for a monochromatic color scheme, wearing matching heels and simple glam.
Considering the last-minute red carpet dress code changes at Cannes, Becky’s look was a reminder that you don’t have to break the rules to make headlines. Though comparatively understated, her classy gown enlisted asymmetry and texture for a head-turning result.
L’Oréal Dinner
As one of L’Oréal Paris’ ambassadors, Becky made a statement at the brand’s May 14 dinner. The actress maintained her streak of monochromatic outfits with an all-black look that combined dinnertime elegance with summer-ready details.
Becky wore a floor-length gown by Thai brand CANITT, which specializes in contemporary womenswear. The black number featured a slight sheer fabric, fitting for the fast-approaching summer heat and aligned with current trends. Becky carried a bag by Roger Vivier, whose designs she frequented during her Cannes spree. Lastly, the actress completed the look with black open-toed stilettos by Giuseppe Zanotti, adorned with a silver buckle almost perfectly matching the details in her clutch.
