Balconette Bras vs Demi Bras
Two constructions that get confused with each other, or chosen between. Here is what actually differs, and which to pick for your shape and your outfit.
Balconette Bras or Demi Bras, in short
A balconette (or balcony) bra has cups that are cut straight across the top, sitting lower on the breast than a full cup: like a balcony. A demi (demi-cup) bra covers roughly half to three-quarters of the breast with an angled top edge that runs from the strap down toward the center. Choose the balconette bra for round, teardrop, bell shapes and wide, square, boat; the demi bra for round, teardrop, bell shapes and scoop, wide. Both start from the same measured size.

How the sizing rules differ
| Balconette Bras | Demi Bras | |
|---|---|---|
| Rule 1 | Size as measured Balconettes are the most forgiving of shape, so a size problem is usually a size problem. | Size as measured Demis are forgiving of shape; a size problem is a size problem. |
| Rule 2 | Full-bust brands Panache Andorra, Freya Offbeat and Fantasie Fusion balconettes carry the shape to K cups in UK sizing. | If spilling Up a cup: the angled edge cutting in is the common failure. |
| Rule 3 | Between sizes Go up a cup: the top edge cutting in is the more common failure. | Molded demis Show a gap fast if the cup is even slightly big; choose a lined-not-molded demi if you're between sizes. |
Both start from the same measured size. The rules above are adjustments; get the starting size from the calculator.
Balconette Bras or Demi Bras?
- Teardrop and bell shapes: the open top avoids the gap a full cup leaves
- Round shapes: sits flat, no gaping
- Athletic shapes in wide, shallow balconettes
- Teardrop and bell shapes: the open top avoids gaping
- Round shapes for a lifted line
- Smaller and mid-range cups under scoop and wide necklines
- Full-on-top shapes: the top edge can cut in and create spillage
- Very narrow shoulders: wide-set straps slip; look for a balconette with adjustable strap position
- Full-on-top shapes: the top edge cuts in
- Very full busts wanting containment: a demi shows more and holds less
Balconette Bras vs Demi Bras: answered
What is the difference between a balconette bra and a demi bra?
Balconette Bras: A balconette (or balcony) bra has cups that are cut straight across the top, sitting lower on the breast than a full cup: like a balcony. Straps sit wider apart, often at the cup's outer edge, and lift comes from the lower cup and wire rather than from covering the top of the breast. Demi Bras: A demi (demi-cup) bra covers roughly half to three-quarters of the breast with an angled top edge that runs from the strap down toward the center. Straps sit slightly wider than a full cup's, and lift comes from the lower cup. It's the go-to under scoop necks and for shapes with fullness below.
Which is more supportive?
Balconette Bras: Moderate to high. Demi Bras: Moderate. Support at larger cups follows the construction, not the label.
Which is better for a large bust?
Balconette Bras range A–K in full-bust brands; Demi Bras range A–G. Round: Balconette Bras; Bell: Balconette Bras; Relaxed: either with care.

Can I own both?
Most wardrobes should: constructions solve different outfits and days. Fit each to the same measured size and let shape decide which you reach for.
