Plunge Bras

Plunge bras sit lower at the centre and position the cups further apart, creating a deep V-shaped neckline. They’re ideal for low-cut outfits and wrap tops where a regular bra would be visible. Historically, many plunge bras have stopped at a D or E cup, as though a low centre and fuller bust couldn’t work together. At She Science, we beg to differ. With the right design and construction, they absolutely can. That’s why we offer a range of plunge styles across an extended size range, including cup sizes rarely stocked by traditional bra stores.

What to Look For in a Plunge Bra

There are a few key things to look for when searching for a plunge bra in Australia. The first is the height of the centre gore - the piece between the cups - as this is what defines a plunge. While a regular bra sits high at this point, a plunge bra sits low, and a deep plunge bra sits even lower. Naturally, the lower the gore, the harder the cups have to work to hold their shape.
For this reason, the band is more important in a plunge style than in almost any other style of bra. Because there is less structure at the centre, the band and sides of the cups carry more of the support, so it’s important that the band sits firm and level to do its job effectively. If you’re an F cup or above, look for a plunge bra with side support panels or a structured moulded cup. These help project the bust forward and inward, preventing the low centre from gaping. Check the strap position, too; plunge cups sit wider, so straps set further out can slip if the band isn’t doing its job.

Plunge Bras in Larger Cups

If you're above an F cup, it's unlikely you’ve found an abundance of plunge bra options to choose from in the past. Thankfully, She Science has plenty of plus size plunge bras in store, specifically from brands like Elomi, Panache, and Sculptresse that all design plunge styles for fuller busts, with deeper cups and firmer bands than standard plunge bras. The Elomi Matilda and Panache Ana are two of the plus size plunge bras our customers love and that our fitters consistently recommend. To browse our styles, use our size filter on this page or view the extended size range.

What is a plunge bra?

A plunge bra cuts low in the centre between each cup, with a wider cup placement. The cups are also angled inward to create a closer-set shape, and they are usually the go-to bra for outfits with a low-cut neckline.

Do plunge bras come in large cup sizes?

Plunge bras do come in larger cup sizes, but they are generally much harder to track down than standard sizing. Elomi, Panache, and Sculptresse all design plunge bras tailored to larger cups with a depth and band strength specifically engineered to support a low centre. To see what is available in your size, use our size filter.

What's the difference between a plunge bra and a balconette?

The main difference between a plunge bra and a balconette is the cup shape and the neckline. While a plunge bra cuts low at the centre and has angled cups designed to be hidden under low cut clothing, a balconette bra cuts straight across the top of the cup and sits higher at the centre, making a balconette better suited to square or scoop neck tops.
