The Iris Longline Strapless Bra
A strapless bra that actually holds a bigger bust. A deep longline band with light boning does the work, so it stays put instead of rolling down.

Find your cup down the side and your band across the top. The cell where they meet is the size you order. A dash means that combination is not made. Or use the finder under the size picker and it chooses for you.

How to measure
Step 1, your band. Run a tape around your ribcage directly under the bust, snug and level, on a breath out.
Step 2, your bust. Bend forward 45 degrees and measure around the fullest part.
Between two bands? Take the smaller band for a firmer hold. It runs true to size.
Why you will love it
Most strapless bras ask a bigger bust to hold itself up. This one is longline, so the work is done by a wide boned band around your ribs rather than by the cups alone — which is why it stays where you put it.
- Wide longline band that sits low on the ribs and carries the weight
- Boning at the sides so it does not fold or roll down when you sit
- Anti-slip lining along the top edge so it stays put without pulling it up
- Converts four ways: strapless, halter, crossed, or one shoulder
- Comes with matching straps AND clear straps, so it works under anything
- Lightly lined rather than padded — smooth under a top, no added bulk
What women say about it
Best bra post weight loss
I am 50 and just lost 100 lbs. 38DD. When I wear this bra, my ladies are back where they were when I was 20.
36DDD or 36F strapless bra
This bra gives me confidence that I can wear off shoulder dresses. I had a baby one year ago and my body changed. If you know your size then order your exact size: my weight is 70kg and my size 36DDD and it is perfect. I do not need to pull it up every time I sit. It is comfortable even if I dance.
Smooth under clothes
Fits perfectly and has a smooth silhouette under clothes.

FAQs about this product
Will it actually stay up on a bigger bust?
That is what the longline shape is for. The band is wide, sits low on your ribs and has boning at the sides, so the weight is carried around your body rather than hanging off the cups. There is also an anti-slip lining along the top edge. It needs to be snug to work — a loose band is what makes any strapless bra slide.
Does it roll down when I sit?
The side boning is there to stop exactly that. It holds the band flat through the middle instead of letting it fold over when you bend or sit down.
Can I wear it with straps?
Yes, four ways. It comes with matching straps and a set of clear ones, and they hook on for a regular, halter, crossed or one-shoulder look. Or leave them off entirely.
Will it show under a fitted top?
It is lightly lined rather than padded, so it smooths rather than adds. The longline band is smooth against the back so there is no line cutting in.
What is the difference between the lace and the plain colours?
Only the fabric on the outside. Black Lace and Nude Lace have the daisy lace overlay, Black and Nude are smooth. The cut, the boning, the band and the straps are identical.
What size am I?
Use the size and fit guide above, or the finder under the size buttons: put in your band and your cup and it picks your size for you. Between two? Take the smaller band — snug is what holds a strapless bra up.
