5 Plunge Bras to Love for Low Cut Dresses

Have you ever fallen in love with a low-cut dress and then felt a sharp pang of disappointment because you couldn’t think of a bra to match? Yep, we’ve all been there, most recently when imagining ourselves in some of the stars’ outrageous met gala gowns, and we can’t help thinking, “but how are her breasts staying in place!?”. We believe that a bra should never stand in the way of the perfect outfit; your bra should stand as the bridge to completing the perfect outfit. Because of this belief, our rise and grind revolves around finding the perfect breast supporting solutions for all of your unconventional outfits so that you can confidently take the risk on the threads that steal your heart.

To help you erase any bad memories of bras standing in the way of you pulling off the perfect outfit, we’ve curated a list of 5 plunge bras you’ll love to wear with low-cut dresses. Whether you’re looking for a backless or strapless solution, something to give you a little more oomph, or a classic plunge bra, we’ve got you covered. These styles won’t let you or your breasts down.

But first, what exactly is a plunge bra?

Wondering whether a plunge bra is the right bra for you? First, let’s delve into what this bra style exactly is. 

Plunge bras feature a deep v neckline with angled cups that draw breasts together. These cups reduce movement and minimise gaping between breasts. The deep v neckline allows for the bra to stay hidden underneath dresses and tops with plunging necklines.

Looking for more information? Check out our guide, Plunge Bras 101, for everything you need to know about this supportive, sexy, and sophisticated bra style.

1. Pleasure State Phoebe Push-Up Plunge Bra

From Pleasure State’s White Label, the Phoebe Push-Up Plunge Bra continues to wow plunge bra lovers season after season. Ticking boxes all around this hybrid bra style offers a plunging neckline AND customised push-up, an ideal option for those wanting to achieve a fuller yet natural-looking cleavage with their low-cut neckline.

Available in Pleasure State’s innovative FMO (for me only) push-up profile, this plunge bra provides the perfect level of push-up for your cup size. The inside of the cups feels like a buttery-soft suede material which helps to hold your breasts in place all day and night long.

All breast shapes will reap the benefits of this style; however, push-up plunge bras are known to work extremely well for Wide-Set breasts as the angled cups draw the breasts together, minimising space and creating cleavage. 

Pssst, if you love the look of this range, we suggest you keep your eyes peeled in September as the Phoebe range is expanding; think of a luxurious bright white colour on corsets, robes and bralettes!

No matter what outfit you’re wearing, one of our lovely customers reckons you can wear this style every day:

“This is the best bra I’ve ever purchased, fits so well, so comfy, looks beautiful, makes me want to buy more so I can wear it every day” Aimee L. (NZ)

2. me. by bendon Deep Plunge Strap + Backless Bra

Designed specifically for tricky back and necklines me. by bendon’s Deep Plunge Strap + Backless Bra may just be a piece of the puzzle that you always longed for but never knew existed. This is the kind of bra that a male would see lying on the floor and think, ‘wtf is that’ not realising that he is looking at lingerie solution gold.

With zero straps and no back band, this bra provides support from its sticky adhesive cups and side wings. Women often go bra-less when they’re working with a backless, low-cut or strapless dress, which can be fine, but it’s often not ideal, but the Deep Plunge Strap and Backless Bra allows you to have your cake AND eat it too by supporting your breasts whilst looking like you’re not wearing any bra at all.

This style is only available for A-D cups due to the fact the bra support relies solely on the sticky adhesive. It’s our duty to ensure that we’re providing adequate support for all cup sizes, which is why we offer Adhesive Body Tape (currently sold in-store only) as an amazing option for backless and strapless outfits for larger breasts (we’ll come back to this style later on!).

3. Pleasure State My Fit Lace Push-Up Plunge Bra

Pleasure State’s My Fit collection was created as a solution for the perfect push-up bra, providing a sexy solution for every outfit. Engineered in 2005, My Fit Lace Push-Up Plunge Bra has stuck around as one of our best-selling push-up plunge bras ever, and it’s not hard to see why. Featuring a soft delicate lace that sits subtly underneath outerwear, suede-touch cup lining that holds breasts in place, adjustable shoulder straps finished with classy Swarovski diamantes at the apex, and of course a plunging neckline suitable to be worn under low-cut dresses.

This style continues to be repeated in Black and Frappe. However, every season, Pleasure State releases this best-selling style in once-off on-trend colours to match the mood and colour palette of the season.

As mentioned earlier, women with wide-set breasts benefit greatly from push-up plunge styles as the angled cups draw breasts together, creating a fuller-looking cleavage. However, we also know that women with round, bell, asymmetric, and small breasts LOVE this style, making it a match for all.

If we haven’t yet sold you on this style, we think this customer review will do the job! 

“AMAZING BRA. If you want to fall in love with a bra, this is it!! Such a comfortable fit with perfect contours, and the lace is so flattering, the push-up feature makes your tatas look like gods gift to this earth and I could shout from the rooftops about how much I love this style - I have 3 different colours. And the matching thong? To die for. This is my all events appropriate bra for suuuure. This bra will make you sigh out of infatuation when you see yourself in the mirror, girlies, I highly HIGHLY recommend.”  Louise V.

4. Fayreform Sculpt Contour Plunge Bra

Comfort and fit were front of mind when our Fayreform designer created this incredible D-F cup plunge bra. The moulded contour cups feature a subtle stretch allowing for great fit and strong support. The material of the angled cups is ideal for a plunging neckline because they are covered with a soft microfibre meaning your low-cut dress, top, or t-shirt will glide over the bra making this style a great option for low-cut necklines.

Fayreform Sculpt Contour Plunge Bra is a great option for those with conical shaped breasts. Conical shaped breasts slope downwards towards the nipples, and the nipples tend to stick out quite prominently (even when your nipples aren’t cold!). This bra will not only draw the breasts together, but the contour cups will create more rounded looking breasts and cover nipples from sticking out or being seen through your bra or dress.

If comfort is your number #1 criterion for your plunge bra, then take it from Marie; this style is a winner!

“THE best. This bra is without a doubt the most comfortable bra I have ever worn. It is now the only bra I wear.” Marie R (AU).

5. me. by bendon Audacious Underwire Bra

It’s chic, it’s sheer, and it gives your cleavage stunning natural shape, meet Audacious Underwire Bra. This is a simple style that could be classed as an everyday basic and a saucy evening style all in one. What makes this style unique from the other plunge bras we’ve listed is that the cups aren’t padded, making this a great style for ladies who prefer a natural shape and no additional bulk that can come from padding. Although the cups are made with a soft sheer mesh material, this style provides a decent amount of coverage as the dramatic plunging neckline is created from the apex of the cups sitting up by the shoulders. It’s clear to see why this style would be great underneath your low-cut dress. With a plunging neckline like Audacious, you’d be able to pull off jaw-dropping dresses like Mindy Kaling’s 2022 lilac met gala gown by Prabal Gurung! 

Most breast shapes will suit this plunging underwire style as long as the wearer is happy with a natural-shaped bust, though it wouldn’t be our top choice for athletic and small breasts where the space between the breasts and the chest is quite shallow and not ideal for underwires. 

Audacious was first released in early 2022, and with the customer reviews it’s had so far, we can confirm it is a crowd favourite!

“Beautiful and comfortable bra. I really love this bra and the matching underwear. They are super comfortable and really lovely looking. The shape is great, and the sheer fabric makes it a little more fun!” Sinead C (NZ).

6. me. by bendon Adhesive Body Tape

Now we know this blog is titled 5 plunge bras to love for low cut dresses, but we couldn’t talk about low-cut neckline solutions without paying homage to the incredible, currently sold out online (but you can still find it in stores), me. by bendon Adhesive Body Tape.

This lingerie solution answers the prayers of women all over the world who have found an outfit that simply cannot be worn with a bra but feel they need bust support. Especially women with D+ breasts who find strapless bras can take a toll on their back after a few hours of wear. This tape is magic; it provides a surprisingly sturdy level of support and a (reversible) breast lift within minutes. 

One of our Bendon team members recently gave the tape a try underneath a spaghetti strap square-neck and low-back dress and was thrilled that her e-cup breasts felt supported all day and night long. She said that this is a style of dress that, without our Adhesive Body Tape she would never have dared to wear! (Our apologies for the slightly questionable/messy strapping, it was her first time!)

If you’re looking  to purchase this tape online or your nearest store is out of stock, then don’t stress ladies; we’ll be re-stocking in June!

Find your plunge bra fit at Bendon

So, you’ve found a style you’re interested in and now need to make sure you purchase the right size. The perfect plunge bra should contain your breasts without any spillage. If you’re interested in a complimentary bra fitting, head to your local Bendon store. Alternatively, check out our online size guide or speak with one of our fit experts on live chat.
