For nearly a century, bra design has clung stubbornly to a crude piece of technology: a rigid semi-circle of bent metal wire. While the rest of the performance and fashion worlds have sprinted ahead with seamless bonding, technical knits, and advanced polymers, traditional lingerie has remained oddly static. The unwritten contract has always been clear—if you want lift, shape, and structure, you pay for it in red marks, chafed ribcages, and that desperate urge to unhook yourself the second you walk through your front door.
Living in Singapore’s relentless heat and humidity only compounds the misery. Metal underwires trap sweat, generic European cuts often gap or dig into petite ribcages, and standard synthetic linings turn into stifling microclimates before you have even made it across the street for lunch.
Which brings me to my recent afternoon at Funan. Tucked inside the mall’s sleek retail stretch is I’M IN, the homegrown lingerie label that has quietly dismantled this compromises-first design model.
The 10-Second Fitting
Stepping into the boutique, the space felt calm, and refreshingly devoid of the intimidating boudoir theatrics that usually accompany luxury intimate apparel. What struck me first, however, was the service.
Before I had even laid hands on a hanger, the sales associate took one brief, practiced look at my silhouette. Without reaching for a measuring tape or subjecting me to the usual awkward hovering, she pulled three distinct styles in what she quietly assured me was my exact size.
She was spot on. Every single piece sat flush against the sternum, anchored firmly along the band without squeezing, and flattered my natural shape effortlessly. In an industry where getting properly fitted often feels like an invasive chore, the whole exchange was remarkably efficient, pleasant, and entirely friction-free.
Precision Engineering Over Bent Wire
The intuition on the shop floor mirrors the obsessive technical thought that goes into the garments themselves. I’M IN was co-founded by Elfaine Tan, whose frustration with lingerie was intensely personal: a prominent scar along her ribcage made traditional underwire styles a source of constant physical pain. Recognising that millions of women navigate similar friction—from post-surgical sensitivity to simple sensory fatigue—she paired up with her husband, Kingsley Peh, to treat bra construction not as mere garment cutting, but as a structural engineering problem.
Peh, who oversees product architecture, bypassed the typical shortcuts of private-label commerce. Instead of sourcing white-label components off regional marketplaces, the duo worked straight from factory floors. They developed custom stainless-steel moulds to sculpt wireless, high-density foam, assembling single designs from up to 50 individual components.
The result is a masterclass in textile chemistry tailored directly to Asian body frames and tropical heat. Rigid underwire metal has been swapped out for clever friction-weave textiles, breathable bonding, and high-density supportive bands.
Putting one on feels fundamentally different to wearing a standard bralette. Most wireless options collapse into soft, unsupportive crop tops after a few washes; but these promise to hold their structural integrity while feeling weightless. Several cuts feature higher-cut side bands and sculpted back wings—a godsend for smoothing underarm tissue and back bulges beneath fine linen tops or fitted T-shirts, creating a clean, streamlined line without pinching skin.
The Disruption of Price Point
What is particularly impressive is how the brand positions itself in a booming global luxury lingerie market that is projected to climb past $34 billion over the next decade. Industry heavyweights like La Perla, Skims, and Agent Provocateur are increasingly forced to compete on material science and fabric technology rather than sheer lace and embellishment.
Yet, while luxury brands routinely charge upwards of $150 to $250 for high-performance intimates, I’M IN manages to keep their pieces remarkably accessible. Holding one in hand, the buttery, heat-sealed finishes, matte hardware, and architectural foam cups look and feel like they belong on a high-end department store rail. The pricing sits at a fraction of that, offering genuine everyday luxury that makes replacing an entire drawer of tortured underwires entirely sensible.
From their origins solving a quiet physical pain point to operating five brick-and-mortar boutiques across the island—including prime retail spots at Jewel Changi Airport and Funan—the brand proves that real innovation does not need to shout. It simply needs to fit properly, breathe in the tropics, and retire the century-old metal wire for good.
