What Makes It Different
Engineered for Full Coverage
Three design decisions that set the 454 apart from every other wire-free bra on the market.
Real Support
Without Wires
The 454 uses seamless support knitting and a knitted power band to deliver lift and shape without a single wire. No poking. No digging. Just support that feels like nothing at all.
Wire-Free Comfort
V-Neckline &
Scooped Back
The V-neckline flatters your natural shape while the scooped back stays hidden under low-back tops. Front-adjustable straps mean you can customize the fit without reaching behind your back.
Flattering Silhouette
The Cups
Are Sewn-In
Lightly lined cups are permanently sewn into the bra — they can't shift, bunch, or fall out in the wash. You get modesty and shape without adding cup size. Finally, a pad that stays put.

Comfort First. Always.
Every design decision starts with one question: will she forget she's wearing it?
"We asked women what they hated about bras. Then we fixed it. The 454 is the result."
What She Said
"I've been searching for a bra like this for years. Full coverage, no wire, and the pads don't move. I ordered three more colors the same day."
"The higher side coverage is a game changer. I wore a fitted top to work and didn't think about my bra once. That's never happened before."
"Every other wire-free bra I've tried rolls up by noon. This one doesn't move. The knitted band is genius. I'm a convert."
