Conical Breasts (Torpedo Shape)
Pointed rather than rounded, with the fullness gathered toward the apex instead of spread across the root. How to recognize a conical shape, why the cups drawn for round breasts flatten or overflow it, and which constructions give it room.
What are conical breasts?
Conical, or torpedo, breasts taper to a point at the nipple: the tissue is firm and concentrated forward rather than spread wide, so the shape has more depth than width. It is common on firm, younger and smaller-rooted breasts and is often mistaken for a cup size problem. Deep, seamed cups with a vertical seam fit; round molded cups flatten the apex and overflow at the top.
How to measure a conical shape: Measure the bust standing straight, tape level over the apex; a conical shape reads true on the tape but often needs a cup letter up for depth in molded styles.

How to tell if you have conical breasts
From the side, a straight or slightly concave slope from the top to a forward apex, not a curve
Molded t-shirt bras overflow at the top in the measured size, then hold air at the sides a cup up
The nipple sits at the most forward point and the tissue behind it is firm
Bra styles for conical breasts, ranked
| Construction | Fit | Why |
|---|---|---|
| Full cup | A seamed full cup with a vertical seam gives the apex room; a molded full cup flattens it and gaps at the sides | |
| Balconette | Seamed balconettes fit; the apex can sit above a low, straight edge, so choose the taller versions | |
| Plunge | Deep at the center with a narrow wire; the cut was drawn for projection | |
| T-shirt (molded) | Round molds are shallower than a cone at the apex: the top overflows and the sides hold air | |
| Push-up | Padding pushes projected tissue into a roundness it does not have and wastes the depth | |
| Wireless | Structured wireless with a deep seamed cup works to about a DD; soft cups flatten the shape |

What goes wrong for conical shapes, and the fix
| Symptom | Fix |
|---|---|
| Overflow at the top of a molded cup | Shape, not size: a three-part seamed cup with a vertical seam; keep the letter |
| Air at the sides in the bigger cup | The cup is now too wide: go back a letter in a seamed, projected cut |
| Wire digs at the sides | Root is narrower than the wire: a narrower plunge or balconette wire, same volume |
Sizing note: Conical shapes measure true on the tape but are projected, so molded cups run a letter small at the apex and seamed cups run true. Buy seamed, keep the measured letter, and treat overflow in a mold as a cut problem rather than a size problem.

Conical vs the shapes it gets confused with
| Shape | How it looks | Cuts that fit | Where it fails |
|---|---|---|---|
| Conical | Straight slope to a forward point; firm; apex is the most forward point | Deep seamed cups; plunge | Molded cups overflow at the apex and gap at the sides |
| Round | Even curve top and bottom; apex centered | Almost any cut | Few; the reference shape every mold is drawn for |
| Teardrop | Lighter on top, rounded and fuller below; apex slightly low | Balconette, plunge, demi contour | Full molds gap at the top |
| Projected (any shape) | Deep root-to-apex distance on any profile | Three-part cups, narrow wires | Wide shallow cups gap at the sides; conical is one kind of projected |
Shapes overlap: a breast can be conical and asymmetrical, or conical and side-set. Fit the shape that is causing the symptom in front of you.
How a conical shape fits at every cup size
| Cup range (US) | What changes | Reach for |
|---|---|---|
| A to B | The point is subtle and most cuts work; molded demis may still show a small gap at the sides. A seamed or spacer demi is the cleanest. | Seamed demi, plunge |
| C to DD | The classic misdiagnosis range: overflow at the apex of a t-shirt bra sends people up a letter, then the sides gap. Change construction, keep the letter. | Three-part full cup, seamed plunge |
| DDD to G | Depth becomes the whole fitting problem; wide-cup full-bust styles built for width leave air at the sides. Look for narrow wires with deep cups. | Seamed plunge, deep three-part cup |
| H and above | Rare at this cup because firm conical tissue usually softens with size; where it holds, only the deep seamed cups of the UK houses fit. | Deep seamed full cup |
Under clothes. Conical shapes read pointed under thin knits in a seamed cup and flattened in a molded one; neither is wrong, and a spacer-fabric cup gives a rounder line without the overflow of foam. Deep V necklines suit the shape because the plunge is its best cut; high crew necks over a full cup show the apex most.
Four checks for a conical shape
- Scoop, then look at the apex: the cup should be deepest exactly where the point is, with no crease above it
- Run a finger along the outer cup: air at the side means the cup is wider than your root, not bigger than your breast
- Bend forward: tissue that stays inside a seamed cup and spills over a molded one confirms the construction diagnosis
- Check the wire end: on a conical shape the root is often narrow, so the wire should stop behind the breast, not under the arm

Conical breasts: answered
What are conical breasts?
Breasts that taper to a point at the nipple, with firm tissue concentrated forward at the apex rather than spread across the chest. The profile from the side is a straight slope to a forward point instead of a curve. The shape is sometimes called torpedo-shaped, and it is a description of depth, not of size.
What bra is best for conical breasts?
A seamed cup with a vertical seam and depth at the apex: a plunge, a three-part full cup, or a seamed balconette from a full-bust house. The seam is what makes room for the point. Molded t-shirt and push-up cups are drawn round and either flatten the apex or overflow it.
Why do my t-shirt bras gap at the sides and spill at the top?
Because a round mold is shallower than a cone at the center and wider than one at the sides. In the measured size the apex overflows; a letter up, the sides hold air. Neither size fits, because the problem is the shape of the cup. A seamed cup with the same volume fits both places at once.
Do conical breasts need a bigger cup size?
Not in seamed cups, which run true to the measured difference. In molded cups the apex often needs a letter up, and the sides then gap, which is the signal to change construction rather than size. Measure standing straight, tape over the apex, and start from the calculator size.
Are conical breasts normal?
Yes. It is one of the common shapes, especially on firm, small-rooted breasts, and one of the most often misdiagnosed as a sizing problem. Most fitting advice is written for round shapes; a conical shape needs the cut chosen for depth, and then fits as well as any other.
