Four engineering details that work together, so you can forget you're wearing one.
Other strapless bras pinch, slip, and dig in within an hour. Sikavia sits flat, holds steady, and disappears under everything — no readjusting, no spillage, no regret.
Hidden molded cups give shape without padding bulk. A 360° silicone grip locks the band to your skin so it stays put from sunrise to sunset — no straps to adjust, no hooks to fuss with.
One seamless shape engineered to mold to every curve from A through G. Designed for real bodies, not averages — total confidence, every size.
A wide seamless bottom band smooths over your ribs instead of digging in. Soft & stretchy knit fabric means no lines, no lumps — invisible under off-shoulder tops, strapless dresses, and everything in between.
Machine wash cold in a lingerie bag, hang dry. Do not bleach, iron, or tumble dry — heat breaks down the silicone grip.

Yes — that's the whole point. A 360° silicone grip strip lines the inside of the top band and locks against your skin, so the bra doesn't slide down even when you raise your arms or move around. Most strapless bras fail because they rely on tightness alone; Sikavia uses grip + a wide bottom band to distribute hold across your whole torso. Customers with DDD+ chests report it stays put past the 6-hour mark with zero readjusting.
Step into it from the bottom up, or slip it over your head — whichever feels easier. Pull the band up until the molded cups sit flat across your chest. Tug the bottom band down so the silicone grip strip lies flat against your ribs — that's what keeps it from riding up. The wide top band should sit smooth across your chest with no rolling. 10 seconds and you're set. No straps to adjust, no hooks, no fuss.
Soft nylon-spandex blend with seamless knit construction and a 360° silicone grip strip along the inside top band for stay-put hold. Removable molded cups inside for shape and modesty. Machine wash cold in a lingerie bag, hang dry. Do not bleach, iron, or tumble dry — heat breaks down the silicone grip and ruins the stretch.
Yes. The silicone grip strip is what makes the difference — it locks the band against your skin so the bra doesn't slide down, even with a DDD+ chest. The wide bottom band smooths over your ribs instead of digging in like a thin elastic. The molded cups give shape without padding bulk, so it sits invisible under everything from off-shoulder tops to strapless dresses. First strapless our customers say actually stays put past the 2-hour mark.
One seamless shape engineered to mold to every curve from A through G cup. The stretch knit + silicone grip work together to fit a wide range of body types in each size — most customers stay true to their everyday bra size. If you're between sizes, size down for a more secure hold or size up for softer comfort. Full size chart below.
