Plunge Bras
A low center gore, angled cups and a neckline that disappears under a V: the plunge is engineered for cleavage and for shapes most bras leave a gap on. Here is how, and for whom.
What is a plunge bra?
A plunge bra has a very low center gore and cups angled inward toward it, so the bra sits below a deep neckline. The angle gathers tissue toward the center (which is why plunges suit east-west and side-set shapes) and the lower gore suits close-set breasts and shorter torsos.
How it's built
| Part | Detail |
|---|---|
| Cups | Angled, often molded or lightly padded; the inner edge is cut low. |
| Gore | Very low: sometimes just a few centimeters. |
| Wire | Angled plunge wire, shorter at the center; wire width varies a lot by brand. |
| Straps | Standard, set slightly wider. |
Materials. Angled wires, sometimes with a flexible center. Powernet wings; firm gore.
Types and variations
| Variation | What it is |
|---|---|
| Molded plunge | Foam, smooth; the everyday plunge. |
| Padded plunge / push-up plunge | Adds lift and cleavage. |
| Unlined plunge | Lace or mesh; shows shape. |
| Deep or extreme plunge | Gore at the bottom of the wires; occasion wear. |
| Longline plunge | Bustier styles. |
Which shapes it fits, and why

Who it's for
- East-west and side-set shapes: the angle brings tissue to the center
- Round and teardrop shapes wanting cleavage
- Close-set breasts a full-height gore presses on
- V-necks and wrap tops
Less suited:
- Bell and relaxed shapes at larger cups: little upper fullness to hold the neckline; tissue slides down the cup
- Anyone needing a tall gore for separation
How to size it
| Rule | Why |
|---|---|
| Size as measured, watch the wire | Plunge wires vary from narrow (Cuup, Freya Deco) to wide (Chantelle); wide roots need wide wires. |
| Freya Deco | The best-known molded plunge runs small in the cup: many wearers go up a cup. |
| Padded plunges | Padding adds apparent volume; size to your measurement, not the look. |
Start from your measured size. Every rule above is an adjustment to a correct starting point: get that from the calculator or the measuring guide.
How it should fit
| Check | What right looks like |
|---|---|
| Gore sits against the sternum | Even a low gore should touch |
| No gap at the inner cup | If the inner edge stands away, the shape needs a narrower or more angled cup |
| Wire ends on ribcage | Not on tissue at the side |
Common problems and the fix
| Symptom | Fix |
|---|---|
| Gap at the inner cup | Not a plunge shape, or cup too big: try side-set/east-west specific plunges with side padding. |
| Spillage at the center | Full-on-top shape or cup too small: up a cup. |
| Wire poking under the arm | Wire too wide: a narrower-wire plunge. |
How to wear and style it
- V-necks, wrap dresses, blouses with a deep button line
- Where a full-height gore would show
Care, lifespan and when to replace
- Wash cool; check the center-front stitching where the wires meet
- Replace when the gore no longer sits flat
Pros and cons
Buying checklist
- Measured size; watch the wire width
- Padding level for the look, not the size
- Gore should touch even when low
