The longline that holds a full bust under the gown
Lift, separation, and a smooth line under strapless and sweetheart wedding or special-occasion dresses. Built for fuller cups. Priced the same in every size: $265.
If your dress is strapless or sweetheart, soft cups and sticky solutions often fail by the first dance. You need lift that stays separated, a neckline low enough for the bodice, and hold through the torso so the gown sits where it was meant to.
Shape Society’s longline corset bra is full-bodice foundationwear for that job. Selected sizes run from 32A to 52F. Built for the fuller-bust bride (about DD through F) who wants structure under the dress she already loves.
$265 in every size. Free shipping for US addresses.
What you already tried (and why it slipped)
Most fuller-bust brides under strapless or sweetheart do not start here. They work through the same short list first.
Soft strapless cups. Comfortable in the mirror. By hour two, the band rides and the cups flatten or merge.
Adhesive or sticky cups. Fine for a photo. Heat, movement, and a full bust pull them off or leave a crease you feel all night.
Soft-control shapewear. Smooths the torso. It does not lift or separate a DD–F bust, so the neckline still collapses while the midsection looks polished.
When those three fail in that order, the underlayer failed, not the dress.
What the wrong underlayer costs you
You need the gown to look like the fitting.
Stay with a soft or sticky underlayer and you often get three quiet fails: the neckline collapses into one line, the first dance shows the slip you hoped photos would hide, and a fitted or mermaid bodice never sits the way it did on the rack. Structure under the bust and through the torso is what keeps the dress you already chose looking like that dress.
The bra a bridal atelier refused to lose
For years, bridal designer Sonni Jackson used this longline as the under layer that actually worked on her fitting floor. She fit hundreds of women into wedding gowns with it. When the product was discontinued, she looked for a replacement. Nothing compared. So she bought the company.
Shape Society is that bra, rebuilt: White, Ivory, and Nude, sizes 32A through 52F.
“So I did what every perfectly rational person would do. I bought the entire company.”
Wearer notes (coming)
We are still collecting real wearer photos and short notes for this page. We will not invent reviews or stock quotes. Until those live here, the atelier floor is the proof we can stand behind.
What it does under the gown
Lift and separation for fuller cups, so the neckline stays clean instead of collapsing into one line
Full-bodice hold from underbust through the waist under fitted and strapless silhouettes
Low front cut for sweetheart and strapless bodices
Low and illusion-back friendly cut, so hardware can sit below the visible line when you check it with your dress
Ivory that can color-match warm ivory, cream, and champagne gowns (White for bright white; Nude for sheer or skin-adjacent layers)
This is structure under a gown. It is not waist training, posture therapy, or soft-control shapewear.
Words you can take to the fitting
Say these out loud to a fitter, mom, or friend. Pick the lines that match your fitting.
“I need lift and separation, not just smoothing.”
“Soft strapless and sticky cups already failed. I need a longline under this neckline.”
“Please check the band against my low back before we pin anything.”
“Ivory against the gown, not white, unless the dress is bright white.”
“I want to see the neckline after I raise my arms and sit.”
Who it’s for
Fuller busts (about DD–F) under strapless or sweetheart wedding or special-occasion gowns
Fitted, mermaid, or soft-bodice dresses that need hold the dress does not already provide
Low-back or illusion-back gowns, when you confirm the band sits below the visible fabric
Anyone who has already tried soft strapless bras, adhesive cups, or soft-control shapewear and watched the neckline fail
Who it’s not for
Shoppers looking for a fashion or waist-training corset
Anyone who wants soft shapewear-only smoothing without bust structure
Dresses that already have strong built-in cups and a soft A-line that needs nothing extra (try the dress first; add structure only if the neckline fails)

Size and color, without guessing
Sizes: Selected sizes from 32A to 52F. Same $265 price in every size.
Colors:
White: bright white and cool-toned fabrics
Ivory: warm ivory, cream, and champagne (the color-match most bridal floors reach for first)
Nude: sheer illusion, lace, or skin-adjacent layers; choose a nude close to your skin
Measure underbust and full bust. Use the charts on Size and Care. Do not order from dress size alone. A bridal 10 is not a bra band and cup.
Plan: Find your size. Choose White, Ivory, or Nude. Check the bra with your actual gown while tags are still on.
Fit check before the day
Try the bra with the real gown, same shoes if heels change your posture.
Leave tags on until you are sure.
Watch the neckline, back, and underbust line in natural light and with flash if that matters for photos.
Do not stack heavy shapewear over a boned longline or a boned dress bodice. Extra ridges and heat are common when two structured pieces fight.

FAQ
Is this only for plus sizes?
No. The run is 32A–52F. We speak first to fuller cups (about DD–F) under strapless and sweetheart gowns, because that is where soft cups fail most often. Smaller cups who need the same longline structure are welcome too.
Will it show under my dress?
Color and cut decide that. Hold White, Ivory, or Nude against your fabric. Confirm the low front and low back against your neckline and back in a fitting, not from a product photo alone.
Is $265 the price for every size?
Yes. Flat $265 across the size run. Free shipping for US addresses.
How is this different from shapewear?
Shapewear smooths. A longline corset bra structures the bust and torso. Use the tool that matches the job. You rarely need both at full strength.
Can I wear it for events that are not weddings?
Yes, when the dress needs the same lift and separation: formal, black-tie, or any strapless or sweetheart silhouette that has to hold for hours.
If soft cups, sticky cups, and soft-control already had their turn, this is the underlayer built for the gown you kept.
