The Full Story
The seamless wireless bra that actually fits properly — because the straps adjust. Most seamless bras are a single pullover piece with no strap customisation, which means the fit is whatever the fit is. The Katie Em Adjustable Seamless Wireless Bra adds fully adjustable straps to the seamless, wire-free format, so you can set the support and placement where you actually want it rather than accepting whatever the bra decides. Wire-free, invisible under clothes, subtle smoothing through the back and sides. The everyday bra for women who have given up on underwires but haven't given up on fit.
In Black and Peachy Nude. SM through XL.
About Katie Em Undies
Katie Em Undies is a Canadian brand making seamless underwear and bras designed for real daily wear. The adjustable wireless bra is their answer to the gap between the comfort of a pullover seamless bra and the fit of an adjustable one.

Good to Know
How is this different from a Coobie or pullover seamless bra?
The adjustable straps. Pullover seamless bras like Coobie are one-size-flexible with no strap adjustment, which means the fit is fixed regardless of your proportions. This bra has the same seamless, wire-free format but with fully adjustable straps — so if you have narrow shoulders, longer torso, or just prefer more or less lift, you can actually set it. Same ease of wear, better fit control.
Does wire-free mean less support?
For everyday wear at a C cup and below, seamless wireless bras provide enough support without the pressure points underwires create. The adjustable straps compensate for the lack of underwire by letting you customise the lift. For larger cup sizes looking for structured support, an underwire bra will always provide more.
Is it truly invisible under clothes?
Yes — seamless construction with no seams at the cup or band means nothing shows through fitted tops, fine knits, or light-coloured shirts. The Peachy Nude is the closest to skin-tone invisibility; Black works under darker colours and thicker fabrics.
Can I wear this as a sleep bra?
Yes — wire-free and seamless makes it one of the more comfortable options for sleeping in. Many women who prefer some support overnight find the adjustable wireless format more comfortable than a sports bra or nothing at all.

Katie Em size guide
Seamless, second-skin comfort in sizes Small to Extra Large. From a fellow Canadian small business, these pieces are soft, smooth under everything, and so comfortable you'll forget you're wearing them (the best compliment a bra can get).
Our fit tip: Katie Em is made with 85% polyester and 15% elastane, so it gently relaxes and moulds to you with wear. If you're between sizes, always size down. It'll feel snug for the first few wears, then settle into a fit that stays supportive and smooth for the long haul.
