Finally threw out my underwire bras. This lifts better and I don't spend my whole day thinking about it. Bought the 3-pack already.

Was so skeptical after being burned by other viral bras. Tried it anyway and I'm genuinely shocked. Feels like nothing, looks incredible.

Got so many compliments at a wedding last weekend. Wore it for 8 hours dancing and it didn't move once. Ordering the bundle today.

Size Guide
Our Jelly Contour Technology™
Our wireless bras use a flexible, gel-infused contour layer that lifts through adaptive contouring — not rigid wire and compression. The W-shaped jelly strip maps to your natural breast shape, creating lift from underneath instead of poking from below. The result: real lift, natural shape, all-day comfort. Zero metal. Zero stabbing.
Fabric & Care Details
Material Composition: • 55% Nylon • 45% Spandex
Care Instructions: We recommend machine washing in a mesh bag and tumble dry on low, or hand wash cold — lay flat to dry. The jelly contour layer is sealed within the cup and will not shift, crease, or degrade with regular washing.
Shipping & Our Guarantee
Our processing time is 1-3 days. Free tracked shipping on all orders. Arrives in 5-10 business days.
30-Day Comfort Guarantee — wear it for a full month. If it's not the most comfortable lifting bra you've tried, return it free.
Perfect Fit Guarantee — wrong size? We'll send the right one at no extra cost. No return needed.
Most wireless bras give you comfort OR shape. Never both.
The Jelly Contour Structure™ inside every Sirencia bra uses a flexible, gel-infused layer that lifts from underneath — the way lift should work. No digging. No rigid cups. No ripping it off by 3pm.
Women who've cycled through a dozen bras say this one is different. Because it actually is.

★★★★★
9 Hours, Zero Marks. Best Bra I've Ever Owned.
After breastfeeding, nothing fit the same anymore, everything either hurt or just did nothing. This is the first bra I've put on and actually forgot I was wearing. Wore it for 9 hours straight. Zero marks. Zero adjusting. I genuinely cried a little.

This Is My Uniform Now.
I'm on my feet for 12-hour shifts. I threw out 4 bras this year because they hurt too badly to finish a shift in. This one I forgot I was wearing. I ordered three more the next day. This is my uniform now.

My Strapless Bra Era Is Over.
Wore it to a wedding — dancing, outdoor summer heat, 8 hours on my feet. It stayed perfectly in place the entire night. Looked incredible in photos. My strapless bra era is officially, permanently over."

I Don't Know How It Works. I Don't Care.
I did not believe wireless could actually lift. Every bra I'd tried before was just fabric draped over my chest. This one shapes, separates, and holds. I genuinely don't know how. I don't care. It works and that's enough for me.

★★★★★
Like a Better Version of Myself.
I've always felt flat and self-conscious in fitted tops. This gave me actual shape without making it look fake or overdone. Subtle, natural, like a better version of me. I've worn it almost every day since it arrived.

At 52, I Was Wrong to Settle.
I honestly ordered it expecting to return it. I put it on, wore it all day, and had no marks and real lift for the first time in years. At 52 I thought comfortable AND lifted was asking too much. I was wrong. I've since bought the 3-pack.

FAQ
Will this actually lift me without underwire?
Yes — and this is the question we take most seriously. The Jelly Contour Structure™ uses a gel-infused flexible layer that lifts from underneath by following your natural breast shape. This is not a bralette. Bralettes are just fabric. Ours has a structured contour layer that creates real upward lift and inward definition — without a single piece of metal involved. If you've been told wireless can't lift, you haven't tried this.
I've bought viral bras before and been disappointed.
What makes Sirencia different? We know this market is full of products that look great in ads and fail in real life. That's exactly why we offer a 30-Day Comfort Guarantee and a free size exchange — no runarounds, no awkward returns process. We only win if you actually love it. If you don't, we make it right. That's the entire business model.
Will it work for my cup size?
Sirencia works across cup sizes A through F. The contour layer was designed to work with natural breast weight, not against it. That said, we'll be straight with you: if you're a larger bust looking for high-impact sports support, a dedicated sports bra will serve you better during workouts. For work, events, daily life, and everything in between — Sirencia handles it.
My body has changed since having kids / gaining weight / getting older. Will it still fit me?
This is exactly who we built it for. The flexible 3D molded cup doesn't force your shape into a standard mold — it adapts to you. Whether your chest is smaller, softer, uneven, or just different than it used to be, the contour structure moves with your body. A lot of our most loyal customers are postpartum women and women 40+ who say this is the first bra that's fit them properly in years.
How do I know what size to order?
Sirencia runs true to size for most women. If you're between sizes, go up one for a more comfortable band, or stay at your normal size for a snugger lift. And if you get it wrong — it doesn't matter. Our Perfect Fit Guarantee means we'll send you the correct size at no extra cost. No return needed. Just reach out and we'll sort it.
Will it stay in place all day — including at events, in heat, while dancing?
Yes. The contour structure holds position because it works with your body's natural shape rather than fighting it. It doesn't rely on adhesive (which fails in heat) or rigid wire (which shifts when you move). Customers wear Sirencia through 12-hour nursing shifts, full wedding receptions, and outdoor summer events — and consistently report zero adjusting required.
I keep patting my chest to make sure I'm actually wearing it. The sensation is so light and unobtrusive that my body just stops registering it. But the lift and shape are definitely there.

My best purchase of the whole year
Looking back at everything I bought in 2025 this is genuinely at the top. Small purchase but massive daily impact. Feel better in my clothes, feel better about myself.

This solved a problem I had for years
I've spent a decade trying to find a comfortable bra that also provides real lift. I assumed it just didn't exist. I was wrong and I'm genuinely glad I found this.

Wore it 14 hours on a travel day
Long haul travel to visit family. This bra went the full day without once making me uncomfortable. I've never been able to say that before.

Still looks brand new after a month of wear
I wash it weekly and it's still holding its shape. The padding hasn't creased, the band hasn't stretched out, the fabric still looks fresh. Durability matters and this one has it.
