Push Up Bra or Balcony Bra for Low Necklines?

The neckline decides, not the label

A low neckline exposes the center and top edge of the bra, so the shape that works is the one that frames that open space without fighting your top. Push up and balcony bras both sit lower than a full-coverage style, but they solve different problems: push up concentrates lift and depth at the center, while balcony opens the top edge for a wider, straighter line.

The supplied product records give enough detail to compare two specific Marlies Dekkers options, but they do not include cup depth measurements or wire widths. Use the descriptions as a starting point, then judge fit in person.

How the two shapes behave under a deep V

• Push up bra: center lift and depth: The pink push up bra (product 1355195) uses small cushions and closely fitted wires to create a deep décolleté. Under a deep V, that center lift fills the space between the cups and keeps the neckline looking intentional rather than empty.
• Balcony bra: a wider top edge and subtle cleavage: The powdery pink balcony bra (product 1355270) is described as creating subtle cleavage with a comfortable, supportive fit. Its straps sit on top of the cups and frame the décolleté, which suits low necklines that run wider across the chest rather than plunging straight down.

When the bra itself is part of the look

Some low necklines are meant to show a bra edge or strap detail. If your top has a wide or square-ish opening, the balcony bra's straps-on-cup design and gold spaceship-inspired ornaments become part of the outfit. The push up bra takes a quieter approach to structure but adds its own visual texture: a flock pattern of Tarot suit symbols and golden polka dots on recycled mesh.

If you want the bra to disappear under the neckline, choose the plainer option and keep the focus on fit. If you want the bra to read as a layer, the decorative details matter as much as the shape.

What the product records confirm

• push up bra: Small cushions and closely fitted wires create a deep décolleté; the bra is available in sizes 70B–80D in bright rose and gold. This is the stronger choice when your low neckline needs center lift and you fall within that size range.

  

• balcony bra: The balcony bra creates subtle cleavage with a comfortable, supportive fit and is available in sizes 70B–85B, including 70E and 70F. It offers a wider size run at the upper cup end and a less dramatic lift, which suits low necklines that frame the décolleté rather than plunge.

  

Size availability is part of the comparison

The push up bra runs from 70B to 80D. The balcony bra runs from 70B to 85B, with 70E and 70F available. If you wear a larger band or a cup above D, the balcony bra is the only one of the two with a confirmed match in the supplied records.

Neither record includes band stretch, cup depth, or wire length, so you cannot predict the exact fit from the size alone. Treat the size range as a first filter, not a guarantee.

A practical way to choose

• Look at the angle of your neckline: A steep, narrow V benefits from the push up bra's center depth. A wider or shallower opening gives the balcony bra's top-edge framing more room to show.
• Decide whether you want lift or a natural line: The push up bra is described as giving a deep décolleté. The balcony bra is described as subtle cleavage. Pick the effect you actually want under the top, not the one that sounds more flattering in theory.
• Check your size against both ranges: If you are above 80D or need a 85 band, the balcony bra is the confirmed option. If you are within 70B–80D, both are available and the neckline should decide.
• Try the bra under the actual top: The supplied records do not include coverage measurements, so the only reliable test is to put the bra on with the garment you plan to wear and check the top edge and center.
