Thirteen years into an acting career, and with stints as a Chanel Friend of the House and former Valentino brand ambassador behind her, Mew Nittha has had more red carpets and fashion weeks than most people could count, and the styling instincts to match. It helps that her fashion sense isn't accidental: she studied Fashion Design before acting, which shows in how deliberate her styling tricks actually are.

Exits matter as much as entrances

Mew treats a backless dress as her go-to move for understated elegance, favoring the detail specifically for the moment of walking away. A slinky black gown from L'Astelle, bedazzled boatneck collar tracing down to an open back, made the case for a night out in Niko, Japan, while a backless black dress with crystal strands draped across the back did the same at a Jasmina jewellery showcase. Her cardigan trick is just as specific: button it almost all the way up, leave the last couple undone, and wear it like a top rather than a layer, as seen with a mustard cardigan and tweed Chanel flap bag in Hangzhou, or a red version paired with a white Chanel 25 on a day out with her kids.

Lace, drop waists, and sheer done right

A lace bralette under an oversized cardigan or shirt is another repeat move, styled as a feminine underpinning rather than literal underwear, whether paired with low-rise jeans and a gold waist chain for a casual day out or a breezy midi skirt on a Bangkok retreat. She's also become something of a case study for the drop waist's return: a white mini dress with a sheer bodice and bubble hem at Sirivannavari's Spring/Summer 2026 show played it soft and feminine, while an all-leather moto-inspired top and matching pleated-hem skirt at another Sirivannavari event proved the same silhouette can go androgynous just as easily. Her take on sheer dressing, a fluid slate-grey button-down and matching floor-length skirt at Aman Nai Lert Bangkok, or a black lattice-patterned set for a Chanel fragrance launch, makes the same point: transparency doesn't have to mean baring everything to read as sensual.
