Wonderbra Ultimate Plunge | Roadtested

December 22, 2013
When Wonderbra asked me to try out their latest lingerie innovation, I had no idea what to expect.  Wonderbra’s most advanced collection with it’s unique wireless support system, the The Ultimate Plunge, has already given us a strapless and the most daring plunge bra utilising a clear central gore, allowing us more freedom with our wardrobe. 
The completely redesigned Ultimate Plunge bra now features a stronger and more supportive band structure, with low central gore cut out promising a deepest plunge ever.  With boobs on the bigger end of the bra scale, I’d be forgiven for being a little skeptical, and so I was keen to see how this new, crazy shaped bra would work for me!

First off, it’s worth noting that the Ultimate Plunge currently only goes up to an F cup, which for me, is in the territory of my pre-proper-fitting days.  I used to wear a 32F before discovering I’m a perfect 30GG, and 32G is my usual ‘compromise’ sister-size, so I  knew that receiving a 32F wouldn’t be the most ideal fit.  However, I knew that I could still judge fairly how wearable the product would be, which was why I still agreed to trial it.

Whilst it’s comically obvious the cups are undersized (slightly!), I was really amazed at how well the bra performed.  Yes, there’s an immense amount of jiggle, but with three quarters of boob proportion on public display, you can’t expect anything less!  The cups, which looked like they wouldn’t be up to much, managed to keep me intact, and through vigorous cavorting the only spillage I suffered was the general bulge/quad-boobing from my boobies being too big – not the bra’s fault.  

Unlike the two aforementioned predecessors, the new shape works as both a conventional strap bra and strapless, which is a huge bonus, especially if you’re flitting between dresses of different styles deciding what to finally wear.  (Yes, I’m one of those.)

Imagine not being limited by your bra!  Flashing bits of cup and centre gore need only be a distant memory of past fashion faux pas.  Being able to wear a sassy plunging neckline without worry or having to go bra-less (here’s looking at me at the UK Lingerie Awards) is a pretty awesome innovation.

What I learnt here was straight: whilst I don’t suggest you wear this as an everyday bra (I wouldn’t feel at my most comfortable wearing it for a day of housework), I will say it’s worth the investment.  Don’t underestimate the Ultimate Plunge by looks, it may appear somewhat flimsy from a photo but in reality it’s a bra with serious backbone. 

Wonderbra asked me to choose an outfit to style my Ultimate Plunge bra with, and I chose this stunning navy all-over sequin playsuit by Motel Rocks.  With it’s deep V neckline and eye catching sex kitten appeal, this is the ultimate weapon of choice for a glamorous night out.

    I watched your fabulous new video titled: Wonderbra Ultimate Plunge Bra – Bounce Test for the third time on YouTube whilst not logged in a bit earlier. It’s brilliant!.
    There was a brief delay before I commented here because I discovered that when I went to watch the introduction video on my own YouTube channel I was confronted with a sign saying “This video may be inappropriate for some users. Sign in to confirm your age :/” After finding that my video could still be watched without logging in where it’s embedded on my blog post titled Outfit Post and Review: Hanes Her Way Women’s Nylon Brief Panties” I relaxed, logged in and headed here to your blog to read the post that went with your fabulous WONDERBRA ULTIMATE PLUNGE | ROADTESTED video!
    What a treat! I’ve since watched your video five more times embedded here. Gorgeous! I love the way your lovely bouncy 30 GG cleavage is supported by and showcases the pretty 32 F cup newly redesigned Ultimate Plunge Bra by Wonderbra. The playful mood of the video is very uplifting (pun intended). It’s been a pleasure learning about the new Wonderbra and seeing how beautifully it works beneath low cut fashions like your very pretty sequined dress.
    What a fabulous review!

    Hi, I would like to know what size are you wearing in the pics. I am from Spain so I have to buy this bra on the internet and I am not sure of my size. Thanks in advance!

    Thank you for this awasome review.
    I wanted to consult with you, I wear a 34G in Freya Deco bras and a 36E in Fantasie Smoothing strapless bra.
    which size do you think I’ll need in the Wonderbra Ultimate Plunge and ultimate strapless?
    (unfortunately they don’t sell it in my country, so I have to order online, and I’m no able to try it on first)

    How did the cups fair without the straps? I bought one and the cups flared out quite a bit without the straps, so I’m wondering about going down in cup size. Thank you!!!!

      Hi Janice, I never wore this bra without the straps and it was quite a while ago I had it, but I vaguely recall the cups did take on an odd shape. I wasn’t wearing it in the best size though so it could just have been down to poor fit in my case. If you haven’t tried the Ultimate Glamour strapless bra I’d fully recommend that one! I reviewed it here: http://beckysboudoir.com/wonderbra-refined-glamour/
