😣 Tent Effect✨ Clean Lines
Reason #1
Goodbye Tent Effect, Hello Clean Lines
Look a Dress Size Slimmer in Any Fitted Top. The jumper hangs straight and you see your waist again.
You've stopped reaching for the fitted jumper. Foam cups push everything up and out, so the fabric sits on a shelf and hangs like a tent. This bra's jelly strips lift from underneath and hold the shape in, not out. The jumper hangs straight down your front and you look a size smaller in the first mirror.

😩 Sags By Noon💫 Lift That Holds
Reason #2
Feel All-Day Lift Like Never Before
No Sagging, No Slipping, No Loo-Mirror Fixes. You check the mirror before bed and it hasn't moved.
By 3pm you're in the office loo hoicking it back up. Foam cups hold for an hour, then let everything drop. Soft jelly strips sit under each cup and don't lose their shape. No sag, no slip, no fixing. You pass a shop window at 9pm and it's where you put it.

😖 Back Bulge🕊️ Smooth Back
Reason #3
Smooth-Back Effect for Instant Confidence
Zero Back Bulge Under Any Fitted Dress. Run a hand down your back and feel nothing but skin.
The fitted black dress stays on its hanger because of your back, not your front. A thin band digs in and pushes skin up over it, and the dress shows it. This bra swaps that strip for a wide flat back panel. Run your hand down your back and it's one smooth line. The dress comes out for Saturday.
BUY 1, GET 1 FREE"I'm a 42F and I'd stopped wearing anything fitted because of the line across my back, not my front. Wore the navy dress to my niece's christening and my sister put her hand on my back and said where's it gone."
— Louise Hartley Verified Customer
😓 Wrong Fit🌸 Fits First Try
Reason #4
Perfect Fit from M to 5XL (Guaranteed)
Perfect Fit for Every Fuller Bust. You order your usual size and keep the first one that arrives.
You've spent more on bras that didn't fit than on ones that did. Most brands stop at a D and stretch the same cup to cover everyone above it. This one is cut in seven sizes from M to 5XL, cups right up to I, each cup shaped for the weight it carries. Order your usual size and it fits the first time.
BUY 1, GET 1 FREE"36FF, ordered my normal size, kept the first one."
— K. Donnelly Verified Customer
🥵 Sticky Cups☁️ Cool And Dry
Reason #5
Stay Cool & Skip The Sticky Cups
No Sweat, No Sticking, No Damp Cups. You peel off a dry bra after the hottest day of the year.
By lunch a foam bra is warm, damp and stuck to you. Thick padding traps heat with nowhere to go. Here the back and sides are open mesh, so sweat dries instead of sitting. Cool and dry on a packed train in July. Two means one's always fresh, and today they're buy one, get one free.

the jumper hangs straight
Cream fitted jumper I'd written off. Put this on, pulled it over, and it hung straight down instead of sticking out at the front. Stood there a while.
didn't touch it all day
Long day on my feet at the salon, no hoicking. Checked the mirror before bed and it was exactly where it went on.
nearly didn't order
Nearly didn't because 'jelly' sounded like a gimmick. I'm a 38G and it holds. There's no line under my work dress now, front or back.
flat back. finally
Ran my hand down my back in the fitted dress. Nothing there.
cool through the heatwave
Wore it through the July heatwave at a desk with no aircon. Took it off and it was dry. Every other bra I own would have been soaked.
ordered my usual size
40E, ordered my usual and it fit first go. Cups hold the weight without shoving it up into my chin. Two came so one's always dry in the drawer.

Third bra I've bought this year. Only one that made the ribbed vest top wearable. I'd been wearing a cardigan over everything to hide the band line.

Bought it because the sizes went up to a 44G and nothing on the high street does without looking like a tent itself. 44FF here, 5ft 3, so everything sits high on me. Put a fitted black dress on for a birthday do and my husband asked if it was new. It wasn't. Six years old.

Was fully expecting to send it back. I'm a 38FF and 'jelly' sounded like something that'd give up under the weight. Put it on under a ribbed jumper I hadn't worn in two years and the jumper hung flat. Not out, not up, flat. Wore it for a 10 hour shift on the tills and didn't touch it once. My mum asked if I'd lost weight.

Bought it thinking jelly strips were a gimmick, I'm 41 and a 38G and nothing without a wire has ever held me. Wore it under a fitted grey jumper to parents evening and the jumper hung straight for the first time in years. Not one trip to the loo to fix it either.

Exactly as said, your usual size is the one to order. Every parcel is tracked and you've got 30 days to try it at home and send it back if it's not right.

Frequently Asked Questions
There isn't one. Most women want a second so one's always fresh in the drawer, and it costs us less to send two in one parcel than to win you back later.
Because 122,212+ fuller-bust women have already ordered and 12,847 of them left a review you can read on this page. If the fit is wrong, you swap it with one email.
They hold. The strips sit under each cup and don't lose their shape, so the lift at bedtime is the lift you put on in the morning.
Find your usual band and cup on the size chart and order the size it gives you. It's cut in seven sizes from M to 5XL, cups right up to I, so nothing is being stretched from a smaller size to fit you.
No. The cups are smooth on the outside and the mesh sits at the back and sides, so a thin top shows your shape and nothing else.
No, that's what the open mesh is for. Air gets through at the back and sides, so sweat dries instead of sitting.
Every order is sent tracked, and the tracking number lands in your inbox the moment it's dispatched.
Yes. Email us your order number and the size you need, and we'll set up the exchange.
